FYI - Watch out for large monitors
I was contacted by a user who was stuck in a loop of "FRM-" messages.
Message like - FRM-41082 cannot resize item
It turned out he accidentally clicked "Window -> Vertically Tile" on the menu.
Which normally is not a problem, but he form window was full screen and he has an extremely wide monitor.
The navigator form went to the full width of the monitor and started generating the FRM-41082 messages.
He closed his session and tried to come back, but got stuck in the FRM-41082 messages loop.
I summarized the screen width was saved for the user in a table.
