The bug being, that the MB event handler named WinClosedHandler is only
called AFTER the save/discard prompt appears.
If it was called BEFORE the prompt (as it should be), using a
WinClosedHandler subroutine to clear the cosmetics would do the trick.
And clearing the cosmetic layer can actually be done in a single statement:
Rollback Table WindowInfo(someid,WIN_INFO_TABLE)
with "someid" being either CommandInfo(CMD_INFO_WIN), FrontWindow() or some
integer variable.
BTW: This also applies to Layout windows, which is actually one single
cosmetic layer.

I hope people agree with me that this is a bug in MapInfo.
