I have about 500 users on 1125se WYSE terminals connecting to a Presentation Server 4.0 Farm. From time to time these users receive a trap error when using ALT-TAB to swap to another open application and once the error is displayed on the screen the WYSE terminal restarts and the user is presented with the login screen again.
I have tried all types of Firmware including 4.4 and 5.0 and have experienced this problem with them all. At the moment we are using 4.4.079 as this appears to be the most stable.
Is there anyone out there who can shed some light on this problem ?
