Poser does seem to be more of a memory hog than I thought it was and they said Win 98 was bad rolling eyes. But unfortunately is not only while rendering, that I could maybe understand, I only have a gig of memory and running XP Pro. But sometimes I minimize to look with Yarp's P3dO for something I know I have and when I come back Poser6 is all yucky! I haven't minimized while rendering yet, I usually take a break from the computer and just let it do its thing. Thank you both for responding. This makes me nuts sometimes and even if not rendering your advise of getting up from the computer Misrael is very good. :-)
