{Believe it or not, sometimes Poser is telling you the truth when you get that error message. I think we sometimes underestimate the amount of room our hard drives need to render and run our software.} I always thought that Windows would adjust the virtual memory as needed. And why does this error message say to "allocate more memory to Poser"? The last I checked, you can't "allocate" memory to Poser on a PC... this is a Macintosh feature!
