I've asked this question of MacDTS, but just at the moment I have a
deadline approaching and I can't wait a week for an answer.

I have a program that brings up a dialog (*not* a dBoxProc window) and calls
ModalDialog to detect the user clicking one of several buttons.  After
the user's selection the window stays on the screen and the program
goes into a "normal" event loop for a while -- it calls WaitNextEvent,
not ModalDialog.  This is supposed to allow the user to select an
action and then swap the program into the background while the program
does its thing.  But Multifinder refuses to swap!

If you patch out the call to ModalDialog, then Multifinder allows the
swap.  This is good for debugging but not so great for the user.

Does anybody know how I can get Multifinder to allow the user to swap
out the program under this condition?  It sounds like the system is
setting a flag somewhere in ModalDialog and forgetting to un-set it.

Here's hoping somebody has noticed this problem before...
