I set my display mode in direct draw to:
dd.SetDisplayMode 1024, 768, 32, 0, DDSDM_DEFAULT

But when I blit, there are weird pictures or "sprite trails" showing up in parts of the screen, but this does not happen if I set it to 16-bit, then again I dont want to use 16 bit, so anyone know how to fix this problem?
thanx........
