hi, I have been trying to do some work in my poser 5 program and have been having over 6 figures in the pictures, but am running into a problem with a low on virtual memory message popping up when I start to render the picture. How can I increase the virtual memory? My computer has a 1.2 GHz and 512 RAM and Win XP so it is a powerful machine, but do I need to add a new memory card or something?
