Application disappearing randomly

[Emad Attia]

Hi all, We are having an issue with a WinForm app disappearing with no warning when the user does some UI actions (clicking, dragging, etc.) on various windows and dialogs. There is no sequence of events that is known to reproduce the problem and we are handling 'unhandled exceptions' through a form. We have looked at memory usage, GDI objects, handles, stack overflows and none seem to be the cause as far as we can see. Any other reasons that could cause such a problem? Any help is greatly appreciated. Thanks very much Emad

Just to be clear do you mean that the Application is exiting (i.e. Quits) randomly or do you mean that it disappears from the Foreground - in other words it's still running but the form is either put at the back of the other windows on the screens or minmized for example?

yeah the application just quits...
