Thanks Malcolm,


The problem is that the user can not cut and paste from any application.

I tried few days ago to add Notepad application to the mentioned
registry but it didn't help.

I will investigate the problem over the weekend and I will let you know
if I find any solution.

General Clipboard Contention Issues

The open clipboard call failed due to contention with Wfshell, a Citrix
utility that enables cut and paste operations amongst the client and
server. This problem was reproduced using Microsoft Excel 97 but was
also present with other applications.

It is now possible to configure the server in such a way that if an open
clipboard call fails, the system retries to open the clipboard a
specified number of times or until the open is successful. It is also
possible to configure a delay in milliseconds between each clipboard
open retry. The following procedure describes how to enable this feature
for a given application:

1. Create the following registry key:

        HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\Current
Version\Terminal Server\Compatibility\Applications\{app name}

where {app name} is the name of the application without the extension.

2. Add the following registry values to the above registry key:

        OpenClipboardRetries: REG_DWORD: 0x20
        OpenClipboardDelayInMilliSecs: REG_DWORD: 0x50
        Flags: REG_DWORD: {num}

where {num} is the application type. Possible values are:

DOS application 0x1
OS/2 application 0x2
Windows 16-bit application 0x4
Windows 32-bit application 0x8
Win16 and Win32 applications 0xC
Any version 0xF

When testing Excel 97, the above settings worked well for Excel (32
retries with a 256 millisecond delay between each). If applications on
the ICA Client device and the MetaFrame server are actively accessing
the clipboard simultaneously, it may be necessary to increase the
settings for "OpenClipboardRetries" and "OpenClipboardDelayInMilliSecs."

3. Restart the application for the new settings to take effect

        Which version of Metaframe and ICA client are you using?

        Thanks Joe for your replay.


        I have only two users which have a problem with Clipboard. All
other are ok.

        Anyway, from server point of view the virtual channel for
Clipboard is enabled in ICA-TCP properties and there is no active policy
which could disable Clipboard.


        The only way on ICA Client, which I know, to disable clipboard
mapping is to remove Clipboard from line VirtualDriver = ... in the
Module.ini file.

        I have checked it in case a user removed this setting (?), but
Clipboard is still allowed in Module.ini file.


        Any other idea how to fix the problem with clipboard?



        Running RepairCBDChain32 which moves the ICA client to the
beginning of the clipboard chain doesn't help as well.

        Make sure the Clipboard Virtual Channel has not been disabled.
Both on the server and via Citrix Policy.

        Some users are having trouble cutting and pasting text from
Notepad on their desktop into published applications. 

        Is this related to C itrix setting? 

        If yes please let me know what I should check.
