For some reason, the versions seem to be getting progressively worse on my copy of Pro. The demo worked fine for what I wanted, there were just a few free flight rotation problems, but I managed to make Quake III in 20 lines

. I was so impressed I bought the full thing, but that version sometimes coloured objects a strange red tint, and the rotation commands still didn't work. Now I have patch 3.1, it doesn't load most of the objects, those that it does load are coloured red, the rotation commands don't work, sphere mapping slows down to a crawl, arrays aren't accessed properly (if at all), the 2d drawing commands are all blurry and emit a strange dithering pattern. Those are all the bugs I've come across so far, since I moved back to DBC for the moment. The only problem with DBC is that the 2d drawing takes so long (3 hours for a screen full of dots, as opposed to 5 seconds in Pro).
Do you have to delete your objects and stuff at the end of each program? I never do, and it still works.
