	I have used GlobalDosAlloc successfully to communicate between
	a DLL and a DOS TSR.  I don't make the GlobalHandle() call though.
	I just copy stuff in/out of the buffer using the Selector from
	the DLL and use the Segment from the DOS Tsr.  I don't know if
	the code you posted is exactly the same as your program but you
	really should be checking the return codes.  If GlobalHandle() fails
	with a NULL pointer then this would explain the behaviour you have
	seen.
