I recently aquired a copy of Lightwave 6.0 (for educational purposes) and on my 98 SE system it doens''t work as well... Well the problem is in that the windows that display the 3d data are very picky and usually they are stuffed, i.e. no display, incorrect display, wierd switching etc, and I was wondering what it was, the opengl driver or what? But mroe to the point I was wondering if this only occurs on win 98 SE machines and not on NT for some odd opengl reason... well thanks for any data relating to this Dæmin (Dominik Grabiec) sdgrab@eisa.net.au
