Screen Corruption with MS-DOS Graphical Program in a Window

 Last reviewed: May 8, 1997
Article ID: Q102538

The information in this article applies to:
  • Microsoft Windows NT operating system version 3.1
  • Microsoft Windows NT Advanced Server version 3.1

SYMPTOMS

If you switch a graphics-based MS-DOS-based application from full screen to a window with a 640 x 480 resolution and an XGA or XGA2 adapter, garbage appears on your screen when you return to your application in full-screen mode. The application is still running, but you cannot see it.

CAUSE

The XGA driver does not correctly save or restore the XGA processor state when leaving or returning to MS-DOS-based emulation.

RESOLUTION

To correct this problem, try to close the application without data loss. If you cannot exit the application using key combinations, use the Task List to close the application.

To avoid this problem, do not switch MS-DOS-based applications from full screen to a window (ALT+ENTER) and do not press ALT+TAB to switch to another application.
