It's because FrmHandleEvent calls FrmEraseForm in its handling of frmCloseEvent.
FrmEraseForm calls the relevent redraw function (the one that reports the
problem).

Subject: Another Debug-ROM catch
I have an application which, when run on the emulator (recent
vintage) with an OS 3.5 debug ROM (ColorDbg.rom, for instance),
reliably generates the following error message:
Form.c, Line:649, Windows cannot be under forms because they
can't be redrawn.
I had been assuming that this was due to the debug ROM forcing
form update events instead of simply restoring saved pieces of
bitmap, to test applications' handling of those events. But it
turns out that a frmCloseEvent, not a frmUpdateEvent, is being
handled when this message pops up.
Can I get some advice on debugging it?
Thanks,
Greg Lutz
