No. I am not talking about the exit bar or the initial size of the window, I am talking about during the processing of an application. Sometimes the processing works just fine, other times an application window will get minimized. I did forget to mention this is only occurring on our CITRIX (thin) sessions. The user will be processing transactions and everything will "look" normal to the user. At some point, the user will "think" the transaction completed (after clicking "OK" or "NEXT"), however the transaction window was really minimized. If you were to click on APPLICATIONS (at the top of the screen), you would see the minimized application in the list of applications. Let me also add that all of the applications are custom written. They are not JDE address book, sales, G/L, etc. This only started happening -after- we applied SP21_F1.
