My approach would to to hide the application:

DECLARE Integer ShowWindow IN User32 INTEGER lnHwnd, INTEGER lnOption
ShowWindow._screen.hwnd,0)

and after the other process is terminated show it again:

ShowWindow._screen.hwnd,3)

The external executable does have a UI with a window displayed in front of my app.

>The problem is that if I switch back to my app before closing the external program, the modal form no longer has the same behaviour in that another form can be activated. The problem here is that the modal form's calling form occupies the entire screen and its "movable" property is set to .F. so the modal form "disappears" behind the calling form and cannot be reactivated. From a user's perspective, the app is hung.
