	I think I will take the Apple party line on this one - YOU CAN'T! You
should not have any need to detect that MF is running.  If you need a particular
'feature' of MF like WNE or the MF Mem routines, then simply test for them and
if they exist you can use them - but that does NOT imply that MF is running.

{I still think Apple should add a isMFRunning field to the SysEnvRec}

	Seems to me that if you have the proper bits sets in the SIZE resource
to tell the O.S. that you are MF friendly/aware and that your application
handles Update/Activate events properly you should have no problems...
