	Icky!

	Not easily at the present time; the simplest workaround is to not
muck with AppParmHandle.

	You know you're running as a project if HomeResFile of CODE 1 is
not equal to CurResFile. Under these conditions, you could conceivably
restore the AppParmHandle to designate that your project (gotten from
CurApName and CurApVRefNum) should be reopened; this may fool THINK C
into reopening the project after you've run it. The safest way would
be to not mess with it at all.
