Recently, I created a scene in Poser 7 and saved it. The I tried to render the scene and P7 froze about halfway. I close the window and re-opened the same scene and when I tired to render it, I got a "Out of memory" error message (and by the way, my machine has 2GB RAM and a GForce GS 7300 video card with 256MB memory). It wasn't a very stressful render, a building and a couple of cars (and not the P7 car in the casino pack). 3 lights and the render was set at low raytracing. I closed P7 and opened P6, opened the saved P7 scene and P6 rendered it with no problems.
