>I have a problem with detecting rom within my app when the main VFP window is restored from icon to normal state. In my app I tried to manage the refresh() and Paint() methods but no one is fired when the main window is restored. Please advise me how can I detect the event of user's managing of main VFP window. I do not want to create the timer and trap the WindowState property of _screen object.

_SCREEN doesn't have events to intercept, so if you don't want to use timer, the next step might be using top-level form design.
