How many times does your Clipboard redirection break up per day?
During my daily job I copy many times a day between my local desktop and my ICA desktop. A few times per day I was not able to paste in my remote desktop. You can disconnect your session, and reconnect, but sometimes only a complete new session was necessary to fix this stupid issue.
After a long time I finally found the solution for this, and also helped for some of my colleagues.
- Open the Registry Editor on the client pc
- Under HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICAClient
\Engine\Configuration\Advanced\Modules\WFClient,
add the following REG_SZ value:
CbChainInterval=<value>
Where <value> is the interval, in milliseconds, at which checks are performed. Supported values range from 0 to 2000, inclusive.
Note: The detection takes at least twice the amount of time specified in this setting.
- Save your changes and restart the Presentation Server Client.
I’ve used the value 500, and this is working like a charm for a few months.
Note: This key must be recreated after upgrading the ICA client.

Does this also fix copy/paste freezing when copy/paste is being done WITHIN a XenApp full desktop??
This is the issue we are having, with no obvious clues in the event log etc.
Don’t know. Basically I used it for a clipboard redirection from client to server, it is a client setting so I don’t believe this will help on the remote desktop.
