hmm, perhaps the windowed version is using a faster display depth than 
fullscreen? the windowed mode is 16bit, while the fullscreen is 32bit? 
usually this is the other way around though, since the fullscreen mode 
can run at any depth, and the windowed mode is forced to match the 
desktop depth.

try running fullscreen without the HWSURFACE and DOUBLEBUF flags? this 
will probably run slower for both windowed and fullscreen, but i'm 
wondering how the speeds will compare for that?

obviously the fullscreen and windowed displays are being setup 
differently, i'm just wondering what that difference might be. you can 
get a bit of information about the display mode by doing this.

	print pygame.display.Info()
