IBM PC730/PC750 - Win/OS/2 session video corruption

Applicable to: World-Wide

Symptom:
IBM PC 700 Series 6877 and 6887 systems may exhibit video corruption in a WIN-OS/2 Full Screen session if ALT+ESC keys are pressed to return to the OS/2 Desktop prior to the WIN-OS/2 session completely loading.

Problem Isolation Aids:
The failure symptom has been experienced when following the steps below:
1. Place the WIN-OS/2 Full Screen session and an OS/2 Full Screen session icon in the Startup Folder.
2. Restart the system and allow it to boot to the OS/2 Desktop. The Windows Full screen session should start minimized.
3. Double-click on the WIN-OS/2 Full Screen session icon.
4. While the system is loading the WIN-OS/2 Full Screen session, press the ALT+ESC keys to switch back to the OS/2 Desktop AND then switch back to the WIN-OS/2 session. The WIN-OS/2 Desktop will be corrupted.

Additionally, the failure may occur when ALT+ESC is pressed between any full screen session and the OS/2 Desktop.

Fix:
When the WIN-OS/2 Full Screen corruption occurs, allow the session to complete loading then press the ALT+ESC keys to return to the OS/2 Desktop. Terminate the WIN-OS/2 Full Screen session. At this point the WIN-OS/2 Full Screen session can be restarted without any video corruption.
