All this talk of HW acceleration reminds me of WinME poblems causing Vue4 and HW acceleration to guarantee that I would loose some work. Luckily, with win2k, I can count on Vue behaving reasonable (now if MS stupid Browser and Media player would just go away, and quit reminding me I need to up date them) Netherworks is right, though, that the acceleration should be switchable. If users had the power to use it, they would be able to do so. I still don't use the Vue 4 acceleration after I get too many polygons in a scene. After a certain point, the machine spends way to much time calculating stuff (and ignoring mouse clicks) Very frustrating. eric
