Hi You don't say whether you are running a Mac or PC, anything about your animation like ..number of figures (P3, P4, Vickie or Mike}, props, size of your texture files but I would guess from what you're saying that you either have a ram problem..not enough or not enough free space on your hard drive. I had this same problem with avis and sequenced stills with my old machine. With my new machine, a gig of ram and 40gig HD for Poser alone I haven't had any problems. I have also found if I'm using Vickie, Mike or some of the newer hair models, it will slow even my new machine down to a crawl with a large animation. The only other thing is to maybe check to see when the last time you defragged your hard drive. Poser seems to work better when your disk isn't fragmented. Hope this might help some. EdW
