what is the speed difference? there is a good chance the fullscreen 
version is waiting for a vertical retrace before doing the double 
buffered flip.

also, check the flags of the surface returned by display.set_mode(). you 
likely aren't even getting HWSURFACE or DOUBLEBUF flags for the windowed 
mode.

	if screen.get_flags() & HWSURACE == HWSURFACE:
		print 'Hardware Accelerated'
	if screen.get_flags() & DOUBLEBUF == DOUBLEBUF:
		print 'Double Buffered'
