No problem. Under SYSTEM PROPERTIES (hit the WINDOWS key and the PAUSE|BREAK key at the same time) you'll find a tab called ADVANCED. Hit the settings button next to PERFORMANCE, where you'll find another tab called ADVANCED. Hit that, hit the CHANGE button for Virtual Memory, click the Custom radio button, then enter 3500 for Inital Size. You can leave Max Size empty if you want, or give it the same 3500 number. Hit the SET button, the OK button, and that's all she wrote. You will have to reboot for it to take effect.
NOTE: This is a TEMPORARY work-around - it may help getting
Poser to do what it wants to do, but may not be a good thing for overall system speed. Change it back once (if) it works out.
Hope this helps.
