1.0 KNOWN LIMITATIONS
__________________________________________________________________

The following limitations might occur or exist in Netscape
Communicator. To view the latest information about known
limitations for Netscape Communicator, click Release Notes from
the Help menu. For information on how to report any limitations,
click Product Information and Support from the Help menu.

1.1 General
------------------------------------------------------------------

  o Netscape Communicator supports the 
    IBM OS/2 Warp Developer Kit, Java(TM) Technology
    Edition, Version 1.1.8. If you have an earlier version
    of a Developer Kit, upgrade to the latest version.

    You can download the latest version from the
    Software Choice Web site:

    http://service.boulder.ibm.com/asd-bin/doc/

  o During installation, if a message is displayed stating
    that you do not have the correct FixPak level
    installed and you have verified that you have the
    correct software requirements (see the README.ICN file
    for installation and configuration information), then
    edit the NS46COMM.PKG file. Delete the following three
    lines:

    FILE
       EXITWHEN      = 'INSTALL&& ("%NSWS%" == "FALSE")',
       EXIT          = NETSCAPEFIXPAK

  o For monitors set to a resolution of 1024 x 768 or
    higher, the default font of Tms Rmn 10 pt. might cause
    overlapping. Change the default font to Tms Rmn 8 pt.
    to correct this problem.

    To change the font:

    1. Click Edit --> Preferences --> Fonts to display the
       Fonts window.

    2. To the right of Variable Width Printer Font, click
       Select.

    3. In the Size box, type or select 8.

    4. Click OK to close the Font window.

    5. Click OK to save your changes and close the
       Preferences window.

  o When using some font sizes, text on some Web pages
    might overlap or appear outside areas defined by the
    background color. To correct this problem, change the
    font. See above for instructions.

  o The Print Preview function is not available within
    Netscape Communicator.

    To preview a print job using Picture Viewer (PICVIEW):

    1. Right-click on the printer object on your desktop.

    2. Select Change Status -> Hold from the pop-up menu.

    3. Print your document from Netscape Communicator.

    4. Double-click the print object to open its job view.

    5. Double-click the icon representing your print job to
       view it in the Picture Viewer metafile viewer.

    Note: Picture Viewer is an OS/2 system utility. If you
          don't have Picture Viewer installed, you can add
          it from Selective Install in the Install/Remove
          folder within System Setup.

    You can choose to delete the print job from the
    printer object, or allow it to pass to the printer by
    right-clicking the printer object, and then selecting
    Change Status -> Release from the pop-up menu.

  o Composer plug-ins are not included with Netscape Communicator
    4.61 for OS/2 Warp.

  o To ensure that Netscape Communicator always uses the specified
    file name when downloading a file, close Netscape Communicator
    and add the following line to the PREFS.JS file located in
    your USERS directory:

    user_pref("os2.replace_dots",false);

  o If your mail and news items do not have the correct date and
    time stamps, make sure that the TZ (time zone) variable is set
    correctly in your CONFIG.SYS file. For more information,
    type the following at a command line:

    view cmdref tz

  o If you plan to install or use a Host On-Demand Cached Client,
    you must install Netscape Communicator into an HPFS partition
    because Host On-Demand Cached Client use long file names.

  o If you experience problems downloading files using a dialer to
    connect to the Internet, check that the port speed of the
    dialer matches the speed at which you are connecting to the 
    Internet.

  o If you have Feature Install installed, you do not have to 
    reinstall Feature Install after installing Netscape 
    Communicator.

1.2 Security
------------------------------------------------------------------

Netscape Communicator uses the Netscape Security model,
instead of the Java Security model used in Netscape
Navigator 2.02 for OS/2. The following limitations occur
as a result of this difference.

  o Netscape Communicator cannot load applets signed with
    the Netscape Signing Tool (SignTool) when these JAR
    files reside in the CLASSPATH. If you attempt to load
    one of these applets, the following error message
    appears on the Java console:

    java.io.IOException: bad zip file format

    JAR files signed with SignTool that are loaded through
    the URL or from a local hard drive directory that is
    not in the CLASSPATH are successfully loaded.

  o Netscape Communicator can load applets signed with
    Sun's Javakey signing tool. However, if these applets
    use the Netscape security APIs (for example,
    enablePrivilege/revertPrivilege), the following error
    message appears on the JavaConsole when you attempt to
    load the applet:

    ForbiddenTargetException: User didn't grant the
    xxxxxxxx privilege.

    To resolve this, have the originator of the JAR file
    sign the JAR file using Netscape's SignTool.

  o Applets and JAR files requiring special privileges to
    system resources (for example, file system access or
    additional network access) must use the Netscape
    security model.

  o When signed applets are loaded from the network, the
    classes must be signed using the Netscape SignTool
    and you are prompted to grant permission.

  o When signed applets and JAR files are in the
    CLASSPATH, you are not prompted to grant permission.
    Permission is automatically granted whether the applet
    or JAR file is signed or unsigned.

  o If an applet needs to download files onto your local
    drive, you are prompted to grant permission. Be
    careful when allowing an applet limited access to
    your file system even if it is a signed applet, unless
    you fully trust the signer. If you allow these files
    to be downloaded or placed in the Java CLASSPATH,
    these applets might gain full access to resources on
    the machine, including full access to your file
    system.

  o The UniversalMemberAccess privilege cannot be granted
    or enabled.

1.3 Performance
------------------------------------------------------------------

  o The help might take a long time to display. Avoid
    opening more than one session of help for better
    performance.

  o If you don't specify an Initial Java Heap (IJH) size,
    Netscape Communicator lets the Developer Kits set the
    default. The Developer Kits do not take into account
    the size of Netscape Communicator when it calculates
    the default IJH size. The default is determined by how
    much memory the machine has. The Developer Kits set a
    default IJH size when Netscape Communicator runs an
    applet. The default memory is reserved by the
    developer kits until Netscape Communicator is closed.

    To set the IJH size:

    1. Click Edit --> Preferences --> OS/2 Preferences to
       display the OS/2 Preferences window.

    2. Click IBM Java Properties.

    3. In the Java Options box, type -ms<number><m or k>
       where number depends on the following, and m stands
       for megabytes and k for kilobytes:

       Note: You can also set the Maximum Java Heap size
             using the option -mx<number><m or k>.

       - If you have 32MB or less of system memory, set
         the IJH size to 4MB (-ms4m).

       - If you have 64MB of system memory, set the IJH
         size to 8MB (-ms8m).

       - If you have 80MB or more of system memory, let
         the IJH size default.


1.4 DBCS Information
------------------------------------------------------------------

  o If you are using the English version of Netscape
    Communicator on a Korean operating system, entering
    text with the NUM LOCK on can cause numbers to appear
    in the text.

  o For some DBCS Web pages to print correctly, you need
    to do the following:
