You might just try letting Windows handle Virtual Memory all by itself. I'm a techie, and never mess with the swap file because I'm timid. But I can't help notice the update Curious Labs made for people who have over 1GB of memory, including the swap file. By the way, I run Poser 4 and Poser 5. Each is installed on a totally separate hard drive from my Windows hard drive. Things have always worked better for me that way.
