BTW, I might be in the minority here, but Poser 4.0.3 is pretty solid on my system with Win2000 Pro. I never even checked the virtual memory until today, but it is at 768 Mb, same as the RAM I have, good choice I thought. I seldom render over about 2400 x 2400, but I did open and render a 460 Mb PZ3 as a torture test.
