If you run W2K make sure that the drive where you installed Poser is included in your virtual memory settings. Then you won't have the memory problem anymore. To do this, right-click on my computer, click properties, go to the advanced tab, click performance options. Then click on the change button. Include the drive where Poser lives. Give it sufficient space, minimum 2 x RAM and maximum 4 x RAM. After a restart you are out of problems. I did this when I had W2K. I did not have the problem in XP (yet). I did some large renders at 4000x2000, 2400dps. I must say that I have 512Mb Ram. Hope this helps.
