You know, I could put up with the slow, if I didnt have to pose blind. If I have more than 1 or 2 figures in a scene-- depending on how high the resolution of the textures are-- I'm posing block figures. It's a misery. I'm fairly sure it's because I have a lot in Runtime. Some program with incentives to buy less and use less. Pentium 2.4 with 2G Ram. I'm stuck right now because my firewire drives didn't work out-- so until I can arrange the loan for my new computer-- I have no more slots in this one-- I can't do the organisation I want to do-- no, strike that, HAve to do, in order to run Poser 5. Divide up into many small runtimes and work out of one at a time. Since I tend to work spontaneously, this takes every bit of fun out of it and makes it a drudgery. If you are having no probs with Poser 5, I suggest you check the size of your Runtime-- however many you run-- If you are under 5Gs, that's the reason you are having no problems. Emily
