If you do move it, by all means use the memory fix as it works exceptionally well for auxiliary drives. Actually, I think that's what it was designed for, so Poser wouldnt' still be trying to render on C. As long as I have about 16Gs available, I feel safe-- and isn't that stupid? However, I have a 26G runtime so maybe not that dumb. Keep posting, we'll figure something out. I know I got some renders done by upping the screen ratio and making the render window as big as it could be. The problem only occurs in rendering outside the display window-- to the best of my knowledge. That action seems to be slightly unstable in all versions of Poser. Emily
