i have win98SE. I now the problem. I start with 128MB RAM later 512MB RAM it was much more better.Millchrs need more RAM.TO make a hole scence with figures clothes architecture..i work now with 778RAM without problems. It only happen when i use global lights with a big scence togehter and render. New PC with DDR333 RAM dont froze with 256MB with 512 it does the scence with GI- without frozing- rendering a complette story pic after pic. BX BOard and new one have no problems to work with win98 ans more than 256MB. If it dont look working for you you can use cacheman a freeware or rambooster freeware too. Hope it helps regards ST
