I had the same problems with Win98SE & Voluptuous Vicki or the Noa Tex. Duron 800, 768 megs of ram. Memturbo would show about 300-400 megs drop during the first render (without any other props besides hair) & would return all after use. When attempting a second, the render progress bar would pop up & then poser would stop. All other programs would work. C+A+DEL would kill poser but I would have to reboot to get another render. Fix: Installed Win2K Pro (as much as I hated to). Set up a perm 800 meg Swap file with a limit of 1500 megs, Dirext X 8.0a for 2K, latest vid drivers & latest VIA MB drivers (Abit KT7-A MB). Boom, problem fixed. Do this with a multi-boot config if you play games. install games under Win9X & install graphics & office apps under Win2K. Just like Win NT 4.0, 2K allocates memory much better than win9X & has a much higher limit. Also, since the kernal has it's own, private memory address range, there are less memory issues.
