Seems to be on Citrix 4.2 reciever as well :

• On an affected client PC, run REGEDIT
• Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\ICA Client\Engine\Configuration\Advanced\Modules\WFClient (64-bit PC assumed) – HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICA Client\Engine\Configuration\Advanced\Modules\WFClient ( 32bit )
• Create a new REG_SZ value and name it CbChainInterval
• Open the newly created value and enter the value as 1000

The values accepted are from 0 to 2000 inclusive and is in milliseconds. I would suggest starting with a value of 500. If this doesn’t work then try with a lower value 400 and so on until resolution.

You need to note that detection of changes will take at least double the value addressed above.
