Operaguy, not sure to whom you were referring for the info. For my setup, when P5 was on a separate drive, it was a USB 2.0 120gig drive with at least 100gig free. System is an HP7140 laptop, 60 gig drive, P4 3.0ghz HT processor, Nvidia 5400 64meg graphics card (though that doesn't matter for rendering, only when working in the GUI). At the time I'm not sure what the size of my paging file was, but it would have been on the C: drive in the default location. I never receive any error messages such as "low on virtual memory" or anything. And at the time it hangs Task Manager shows only about 200k of ram in use out of my 1gig. An easy way for me to make it happen was to place two of Hankster's SS7 Supercars in a scene by themselves. Each has a 400+k poly count I think. When I re-installed on the C: drive I could then render 2 of those in the same scene, but a third one would hang at "Adding Objects" as before. Which is always why it seemed to be poly-count related.
