If you specify System 6.0 or later (preferably 6.0.2 or later), you can
simply write it to use the MF WaitNextEvent call instead of GetNextEvent.
Also, why lock the program out of the net when a DA is open?  You still
had control of events in your program when a DA was opened.  If you removed
this limitation to the program, you wouldn't have to worry about MF running
or not.  Just make sure your program can handle suspend and resume events, 
can run in the background (very easy -- just set the "can background" bit and
be prepared for null events), and your program will work under both finder and
MF.
