hi Could anyone shed some light on the following? 1. In fullscreen mode you shouldn't have surfaces larger than the screen; is that so with windowed mode? Will I be safe with a 2048x2048 surface, yet have only a 100x100 primary surface? I rarely use windowed mode... ;) 2. Memory access. When in 24bit or 32bit mode you can read the Red Green Blue values easily - BGR or ARGB/RGBA - but what about 16bit? I want 3 (0-255) values from 2bytes in the array - WTF? how'd I do that? Any help is much appreciated... Jack
