Installation Instructions for the ICA Win16 Client
---------------------------------------------------
See the Citrix ICA Client Administrator's Guide for step-by-step
instructions for installing the ICA Win16 Client.


Limitations and Known Issues
-----------------------------

1. The number of ICA sessions you can have open simultaneously 
   is limited to three sessions plus the Remote Application 
   Manager window.

2. Simultaneous audio: If you are running multiple
   ICA sessions, you can play sounds on only one 
   session at a time.  

3. If you choose color cursors, they are rendered
   in the client window in black and white.  

4. If you install a Web browser after installing the 
   ICA Web Client, you must reinstall the ICA Web
   Client. The Web client component (Netscape Plug-In)
   needs to be registered with the browser so that when you select
   an ICA file in an HTML file, the browser knows what to run to
   invoke the ICA file.

5. Multiple-session OS/2 Mode parameter:

   When an ICA session is minimized, it goes into a sleep mode,
   freeing up system resources for other applications 
   or sessions. If the user is doing anything in the 
   session when it is minimized (for example printing or 
   copying files), session performance slows down. 
   If the user is connected to the 
   session through a modem, or is doing a 
   time-dependent activity, the sleep mode can cause problems.
   To increase the user's flexibility in choosing when 
   the session will sleep (if at all), you can add an
   extra flag to the Appsrv.ini file called "OS2Mode."
   Add the OS2Mode parameter at the end of the [WFClient] 
   section of the Appsrv.ini file with one of the 
   following values:

   OS2Mode=0	This results in 100% CPU utilization at all times
   OS2Mode=1	CPU utilization drops when the session is minimized
   OS2Mode=2	CPU utilization drops when the session 
		window is out of focus or minimized

   Any other value defaults the setting to OS2Mode=0.

   By default, the Appsrv.ini file does not contain the OS2Mode 
   entry and thus defaults to sleep on minimization.

   Note: The Citrix ICA Client program group is not created under
   OS/2 unless you run the client setup from a full screen 
   or window session of Win-OS/2.

6. ICA Win16 Client regression:

   You cannot connect to a Citrix server using the IPX, SPX, or NetBIOS
   protocols after installing version 6.20 of the ICA Win16 Client 
   (the version shipping with MetaFrame XP, Feature Release 1) in the 
   following circumstances:

   *  If you install version 6.20 of the ICA Win16 Client on a client device
      and then install an earlier version of the ICA Win16 Client. Attempting to 
      connect using the earlier version of the ICA Win16 Client will fail.

   *  If you install and then uninstall version 6.20 of the ICA Win16 Client,
      and then install an earlier version of the ICA Win16 Client.

7. To use version 6.20 of the ICA Win16 Client with MetaFrame for Windows
   Version 1.8 on Windows 2000 servers, the server must be running Service 
   Pack 2 for MetaFrame 1.8. If you use version 6.20 of the ICA Win16 Client to 
   connect to a MetaFrame 1.8 server that is at Service Pack level 1, the
   connection will be dropped the next time you attempt to connect.
