    I am thinking that ON SHUTDOWN would be used for _SCREEN (i.e. the application) when you click X (upper right) or click CLOSE from the controlbox (upper left). ON FINISH does not run in this case.

    The _SCREEN menu is enabled when you click on it. However the menu displays as disabled when a form (non-modal) is active giving the impression that the _SCREEN menu is not accessible.
