SYMPTOMS
One or both symptoms may occur in Windows NT 3.51:
- When you log on, log off, or shut down Windows NT, Program Manager
does not appear, or disappears. When you press CTRL+ALT+DEL, the
Windows NT Security dialog box does not appear. Network connections
to the Windows NT computer can still be made.
- Program Manager disappears and is not in the task list. Programs
already started are functional and network connections to the
Windows NT computer can be made.
CAUSE
This problem occurs when the following events occur:
- Process A creates cursor
- Process B references cursor
- Process A exits
The cursor still points to the freed pointer of process A. If the freed
pointer is uncommitted, any call to FindExistingCursorIcon results in
memory access violation and the calling process is halted.
RESOLUTION
To correct this problem, install the latest U.S. Service Pack for Windows
NT version 3.51.
STATUS
