I got it now. I was just doing it wrong. A fix is enclosed, although there may be other lurkers of a similar nature.

Note to Dan: This is a case where 
	
	self world displayWorld
or
	self world whatever

may not yield the expected results. In this case the HaloMorph's world wasn't The World and wasn't ready to deal with a world-like display.

Cheers,
Bob
