I have the same problem - too much virtual ram - your page file size greater than 3 gb and poser freaks - every time or two I render a large scene, I have to increase the page file / virtual size to get a render without running out of disk space (which is what poser says when it gets lost and can't see all the ram and page file even though it is not using all of it) - after I go above 3 gb virtual / page file size, reloading poser gives exactly what you are seeing - if I don't reload poser, it will go on up to 4.095 which is where Win 2000 tops out - if I drop the page file size (go to settings, control panel, system, advanced, performance, etc and reset to below 3000) and reboot to have it take effect - the problem goes away - quirky but can be worked around - I got into this recently when I bought a new high-end computer - I am trying to get poser to fix the bug but haven't got them to yet - Ted
