Our company is running an ERP Software (Encompix) Client\Server system. We have users who access this application using Citrix. The system is working fine exept for an odd issue where when a user clicks the Quick Lauch Desktop icon to minimize all then attempts to go back to the application the screen is blank. This does not occur when running the client directly only when running the application from Citrix. I have seen several related issue posted on Citrix site, but none directly related to Desktop button. The application uses multiple windows as you drill down thru data. Server 2003 TS/Citrix Presentation 4.0. Clients running XP SP2.
