We applied the "Hotfix Rollup Pack 4 for Citrix XenApp 5.0 and Citrix Presentation Server 4.5 for Microsoft Windows Server 2003 64-bit Edition" on Monday and ever since then the users are having problems with the ICA session.
When they log on to the their application, which is a Server Desktop, this launches without problem and the users are able to work away without fault but if they try and minismise their Citrix session and go to full screen again they cannot see anything. All that they can see if the Window and the title bar.
Also if you try to go Resize Window and select "Custom Size" on the client you receive a message saying "Not enough memory to perform scaling. Quit some of your active applications, and try again" and this is depsite the user having no applications open.
Can anyone offer me any advice on how to resolve this ?
Many thanks in advance
