Hi All,
I have a situation with a couple of pices of software that when started up they occasionally will not appear on the screen. They are running in task manager and if shut down and restarted they are OK and all runs fine. This is random timing on different PCs with 2 different pieces of software. Microsoft Dynamics RMS POS and MYOB Retailmanager POS. All machines are running win XP Pro with sp2 or later. This has been happening all the way back since xp sp1.
Any ideas would be greatly appreciated.

A device driver can cause this.
All processes consist of both use mode and kernel mode portions. When a process terminates the kernel mode portion will remain in memory (and Task Manager) until all device I/O is complete. If this was not done some rather nasty things, such as a system crash, could happen. In this case all I/O is supposed to be aborted, but some device drivers do not handle this situation very well and this does not occur. In this case a program could remain in Task Manager long after it was closed.

Some application faults can also do this.

An updated device driver or application may solve the problem.

Thank you for your reply
Would this also be the case when this occurs only when the application is started?
This problem never appears to occur when the application is closing only when it is first started.As soon as the application is closed in Task manager it will always opens immediately the very next time.
