Hi Larry:

I need the event just for that. I have maked a class based in timer control and I create an object in the main prg of my app, then in the mousemove event of the forms I reset a property of my object to sys(2) value.
The object stays in background comparing (in the timer event) his property with the current sys(2) value, if the comparison surpasses certain value, the app shutdown itself.
Well, the mousemove event is not sufficient to determine activity in the main window. Do you know something in the menu that I can consider?
I need to determine if the app is waiting in a open browse window or in a wait window status, because sometimes the users leave the application in this status and the object don't work.

Thanks again
Pedro
