OK, I am happy that that it works for you. Actually, it works in principle <g>. In my case, it worked every time I needed it, which is good enough for my purposes.

However, I am not sure, but I think that if the user left a MessageBox() open, the Timer object will not fire.

Worse, if the user left the form with pending changes (and went to eat lunch), a call to goProgram.OnQuit() (goProgram is the application object in Visual Extend) will - of course - ask the user whether he wants to save the changes. It will not quit immediately.
