Thanks for all your answers. By the way, am I the only one here who never experienced a single serious crash with Windows? I had 98SE, now I'm running XP home, and they run smoothly and without problems at all. I write all day and run Bryce in the background. With priority set to "real time" Word becomes a little awkward, but that's all. Then, I have to admit that so far I haven't seen so much improvement in rendertimes. Have to do a test. Thanx again.
