Yeah, don't know what they did.... Last night I was reading all about Open GL, and it seems to be hailed as something very solid and reliable. I hve no problems at all with anything I have which uses Open GL, except Vue 4. With my VooDoo 3 card, everything, including Vue 4 does great with Open GL. When I upgraded to the most recent driver for VooDoo 3, the Open GL in Vue 4 went to pot, though every other app worked as normal, and the few games I have (Soul Reaver, Quake II, Diablo) were smokin'! Of course, Vue 4 didn't like the newer driver at all in Open GL, so I reverted to the original. I was seeing things similar to the above, but alot of the time the viewports would simply gray-out. I wonder how many people are downloading the Vue 4 demo, seeing a bunch of crud on their screens, not looking into the problem, and simply uninstalling it?
