Known Issues with Acrobat Reader 4.0
------------------------------------

General Information
-------------------
1.  Using NCD PC-Xware:
    A pink tint will appear when Smooth Fonts is turned on in General
    Preferences and the default visual is TrueColor 5-6-5 (RGB) in 16-bit mode
    (this is a PC-Xware problem).  This affects only the display, not the print
    result.
    SOLUTION: Change to a different visual (8-bit or 24-bit) or turn off the
    Smooth Fonts option.

2.  Acrobat Reader will not run correctly from a directory where the "pwd"
    command fails.
   
3.  We recommend you remove the file $HOME/.acrorc before running Acrobat 4.0
    for the first time.  This ensures the default preference settings are used
    when you first run Acrobat 4.0. This is not, however, a necessity, and may
    actually be undesirable if you wish to continue running Acrobat Exchange 3.0.    

4.  Files listed in the File menu are "recent files" and depend upon exact path
    names. If you open a file in a session using automounter and the
    automounter goes down, attempting to open the "recent file" will give a
    "No such file or directory" error.  This also occurs when the file is moved,
    renamed, or Reader is run from a different machine that does not have the
    same file systems mounted.

5.  To prevent temporary files (for instance opened from the Web) 
    from appearing in the "recent files" list, set your mailcap entry 
    as follows:
   
    application/pdf;acroread -tempFile %s

6.  Acrobat Reader does not warn the user when the preferences file cannot be
    written. Please make sure '$HOME/.acrorc' is writable if you wish to save
    preferences.

7.  Some Window managers may work better than others. Specifically, we have
    tested CDE, KDE, and Openwindows.
  
8.  Users cannot print password-protected PDF documents to PostScript from the
    command line even though they are able to print the files from Acrobat
    Reader.
  
9.  When operating in a heterogenous network enviroment using Novell servers, we
    recommend you avoid giving PDF files long names (greater than 32
    characters). A Novell server displays the long file name to a Macintosh
    user, but the Macintosh Operating System prevents Acrobat from opening the
    file. This is not a problem on Windows.
  
10. Modal dialog boxes may appear to be "buried" behind the main document
    window.  When they are behind the main window, they are still active and
    prevent the user from doing anything. To bring the dialog to the front,
    click anywhere in the main window. You can now dismiss the dialog and
    proceed.
   
11. At the command line, type 'acroread -help' or 'acroread -helpall' for more
    information on command line options. Note that when using these command
    lines you must still supply a DISPLAY variable if one is not already defined 
    in your environment. 

12. On a Tektronics X-Terminal:
    If displaying a document in Full Screen mode using a black background, a
    small white line will appear along the bottom and right edges of the
    background. This is due to a problem in the olwm running locally on the
    X-Terminal and is not an Acrobat bug.
  
13. Characters in PDF files that are not part of the ISO8859 encodings will not
    display when the text is selected and pasted elsewhere. This is most notable
    with the Registered and Trademark symbols. Printing is not affected and will
    work fine.
   
14. Printing: no document printed and/or error in lp log.
    When you lp foo.ps, it creates a symbolic link from the spool file to the
    foo.ps file.  This saves space on the file system.  Unfortunately, Acrobat
    creates a temporary file to spool, writes the PostScript out, and then
    deletes the temporary file before the lpd process can get hold of it.
    SOLUTION: Include the "-c" option (copy) on the lp or lpr command in the 
    print dialog box.  This forces the lp process to copy the file to the spool 
    area instead of making a link.

15. In Acrobat 3.0 and later it is possible to give a PDF file attributes for how it 
    should open (with or without Tool bar, etc.)  To make Acrobat ignore the 
    "Open" settings, keep the CTRL and Shift keys pressed down when 
    clicking OK in the File > Open dialog box.  For example, when opening a file
    which has been set to hide the Tool bar, it is not possible to then show the
    Tool bar for the file once it is open. If you need the Tool bar displayed, 
    you should close the file and re-open it making Acrobat ignore the "Open" 
    settings. 

16. Launching external applications / Security - PDF files may contain
    instructions to launch an external application or to open a non-PDF
    file.  To enhance the security of PDF files, Acrobat Reader version 4.0
    will prompt users with an alert before launching
    an external application, an executable file or a command.
    The alert will say: "Acrobat is about to launch this application: "
    [Application] "Allow this action (yes) or all actions to all
    applications (all)?"  followed by three buttons, "Yes", "No", and "All".
    - Choosing "Yes" will allow only this instance of this action.  
    - Choosing "No" will prevent this instance of this action.
    - Choosing "All" will allow all instances of all actions, thus
    disabling the alert until Acrobat is exited and restarted.
    
17. Using Acrobat Search. If you want to create full text search indexes that 
    can be reliably used across platforms, you must use ISO 9660 file naming 
    conventions for the indexed files (8.3 uppercase, restricted character set).  
    If you don't use such names, the UNIX Reader will attempt to guess what the 
    Unix filenames are. This causes delays in searching, and may result in the
    file not being found.
    
18. The select graphics tool and column text select tool are nested under the 
    select text tool. To select one of these other tools, click and hold down 
    the select text tool button, then drag your mouse over to the tool you wish
    to use.

19. Although there is a "Use Page Cache" option, it is disabled inside the
    Viewer for 4.0. It will be enabled for 4.05.

Known Issues for Acrobat Reader Working with Netscape
-----------------------------------------------------

ACROBAT WON'T LAUNCH. If you encounter problems where PDF documents do not view 
correctly in Netscape, Netscape hangs, or document transmission stalls, you may 
disable PDF viewing in the Netscape window and use the viewer as a "Helper Application".

To disable PDF rendering in the Netscape 3.0 window:

1. Pull down the "Options" menu item and select "General Preferences".  On the
   "General Options" dialog, select the "Helpers" tab item.  Find the item in
   the list of helper applications that looks like the following: 

      application/pdf      Plug In : nppdf.so

2. Select this item. 

3. Select the "Edit ..." button to modify this entry. In the dialog box, select
   the item marked "Application" and enter the pathname to the Acrobat Reader 
   product along with the "%s" field identifier for the temporary file name. 
   For example, if Acrobat Reader is installed in /usr/local/Acrobat4 then
   enter the following in the text box for the application:

      /usr/local/Acrobat4/bin/acroread %s

4. Select the "OK" button in the "Netscape Helper" dialog box. 

5. Select the "OK" button in the "Netscape: General Preferences" dialog box. 
   The view in Netscape window feature has been disabled and Acrobat will act
   as a Netscape helper application.
   
   

SOME FORMS CAUSE "SAVE AS" DIALOG Some forms cause the Save As dialog to come up. 
This is because certain forms return Forms Data Format files (.fdf) and 
Netscape is not set up to handle this mime type. This is easy to fix; following
are directions for Navigator 4.x:

-Bring up Preferences dialog by selecting the Edit menu, then the "preferences"
menu item.
-Under the Navigator section, select Applications.
-Click on the New button.
-For Description, type Forms Data Format
-For Mime type enter: application/vnd.fdf
-For Suffixes enter: fdf
-Click Application
-Type /usr/local/Acrobat4/bin/acroread %s iconic (note: your path may vary)
-Click OK

Navigator 3.x:
-Choose General Preferences from the options menu
-In the General Preferences window that appears, click the Helpers Tab.
-Click "Create New Type"
-Mime Type: application
-Mime SubType: vnd.fdf
-Click OK
Now application/vnd.fdf should be selected. If not, scroll to it in the File type list.
-Under the text field "File Extensions, type: fdf
-Click "launch the application"
-Type in the application text field: 
  /usr/local/Acrobat4/bin/acroread %s iconic (note: your path may vary)
-Click OK

Netscape is now ready to accept forms data format.
   
RUNNING IN 256 COLORS OR LESS. Often the viewer may launch in greyscale mode 
when running inside of Netscape as a plugin. This will happen when your default 
visual has a color depth of 8 planes or less (PseudoColor for instance).This is 
because Netscape does not "grab" enough colors for Acrobat. You can work around 
this problem by launching an instance of the Acrobat Reader and displaying it on 
the current screen before launching Netscape. Netscape will then use the Color Map 
that Acrobat has created and will allow the viewer to run as a plugin with enough 
colors. This won't be an issue if you are running with 16 or more color planes.

CAN'T SUBMIT FORMS FROM NETSCAPE. Submitting forms on the web will not work if 
Netscape has warned you that it found a lock file in the .Netscape  folder. 
This warning (which occurs when you first launch Netscape) usually means you have 
another copy of Netscape running. You may fix this problem by insuring that only 
one copy of Netscape is running. If a lock file is left around because of a Netscape 
crash, you may simply delete the .Netscape/lock file.


Solaris-Specific Information
----------------------------

1.  Text colors may change depending on zoom factor. This occurs when working in
    Solaris on a Sparcstation with a CG14 frame buffer and is a known problem
    with the CG14 frame buffer. Please contact Sun Microsystems for a patch.
    The following patches are available and should correct the problem:
  
      Solaris Release      Patch id
      ---------------      ---------
           2.5.1           103794-01
           2.5             103074-02
           2.4             101922-15
           2.3             101594-18

2.  A segmentation fault will occur when launching Acrobat Reader if your
    PSRESOURCEPATH includes /usr/openwin/lib/X11. This directory does not
    contain Type1 PostScript fonts and should not be included in the path
    statement.

3.  We have experienced crashes while trying to fill in forms using the
    X server that ships with _all_ versions of Solaris 2.6. The workaround
    would be to run the X server on another machine, or to run on Solaris
    2.7 or 2.51.

4.  There is no search functionality available for the x86 Solaris version
    of the Acrobat Reader.


HP-UX-Specific Information
--------------------------
  
1.  You might receive warning messages indicating missing fonts. There are
    several messages you could receive depending on your configuration.

    - You are displaying on an X server that has no HP-ROMAN8 font defined. The
    message you receive is:
  
      Warning: No fonts available with charset "HP-ROMAN8", using "ISO8859-1"
   
    In this situation, upper-ascii characters will display incorrectly. To fix
    this, change your language to an ISO8859 language
    (e.g., setenv LANG american.iso88591).
  
    - The variable fontList is specified and its encoding doesn't match the
    encoding of the application. If you specified an ISO font list, you
    will receive an error that says the encoding for fontList doesn't match
    the locales encoding. You need to change your LANG variable as listed above.
   
    - The Helvetica used by the Motif toolkit is not available on the system in
    the hp-roman8 encoding. The message you might receive is:
  
    Warning: Cannot convert string
   "-adobe-helvetica-bold-r-normal-*-*-120-*-*-*-*-hp-roman8" to type FontStruct
  
    This occurs when you are running on HP but displaying on a non-HP system. To
    fix this, set an application resource for fontList to specify a font that
    exists on the system.

2.  The HP Motif library uses different virtual key bindings than Sun's. As a
    result, when running on a Sun and displaying on an HP, the keys for
    DeleteLine, DeleteChar, InsertLine, and InsertChar may not be properly
    defined by default. You can tell if you get warnings of the form
     'Warning: cannot convert string "<Key>DeleteChar" to type VirtualBinding'.
    One consequence of this is that the Esc key on some HP keyboards will not
    work to exit Full Screen mode.

    To fix this, load a file with the appropriate key bindings using the
    "xmbind" command.  See the man page for xmbind for where it looks for the
    file. Check the bindings using  "xprop -root | grep BIND".

    The resulting string should include hpDeleteLine, hpDeleteChar,
    hpInsertLine, and hpInsertChar.
    
3.  Support for viewing/printing files with embedded ICC profiles, a new feature
    of Acrobat 4.0, is not supported on the HP platform due to compiler issues.
    Currently, if you try to print a file with an embedded ICC profile, your
    viewer may display a bus error, and possibly crash.
   

AIX-Specific Information
------------------------

1.  There is a new Netscape browser plugin for AIX. It should be considered beta
    quality, since it was added just before ship time. When using Acrobat as a 
    plugin under AIX, be aware of the following caveats:
    A) Acrobat will seem to launch again every time you view a new PDF file.
    B) It works best with Netscape version 4.05 or 4.08. If you use it with
       Navigator 4.5, you may experience crashes if you try to load more
       than one PDF file.

    We plan to have these issues fully resolved for Acrobat 4.05.


IRIX-Specific Information
-------------------------

None at this time.


OSF-Specific Information
------------------------

None at this time.


Linux-Specific Information
--------------------------

1.    The Acrobat Reader for Linux  was built on a 2.0.0 kernel.

2.    There is currently no search functionality available for the Linux Acrobat
      Reader. 
      
3.    The current Reader is "libc" based as opposed to glibc. This means that
      the Acrobat Reader has been linked with libc.so.5 as opposed to libc.so.6.
      The repercussions of this are mainly that if you are using a "glibc" based
      version of Netscape, you will not be able to launch the Reader as a 
      plugin. Currently, the rpm version of Netscape is glibc based.
         Since things are moving in the glibc direction, we will be providing a
      glibc linked version of the Reader in the 4.05 version.
