FileMaker Pro 16.0.3)
After running a script that calls three subscript in another database to perform several tasks I get an empty screen. The screen content can be brought back by moving the mouse downwards on the empty screen. (The layout is a form so there are no scroll bars).
A window refresh either in the script or called from the menu does not cure the problem.
Does not occur on Windows.
Switching the toolbar or the formatting bar off and then on again in the same script restores the screen.
