When I compiled the following, no bitmap came up, why?(I deliberately put my includes in quotes)
It''s generally not a good idea to load a bitmap EVERY CYCLE THROUGH YOUR MAIN LOOP. I think that''s your problem. Perhaps you could do something to move it to your Init? Anyway, happy coding and enjoy.
