Hitting control-alt-delete on windows Xp at least will let you see the memory use of each application. In my last gallery image the file is only about 80-some mb's, but memory use for Vue alone was often from 600-700mb's of my 1gb, and with that ran over physical memory (windows OS using up the rest). Turning off the OpenGL stuff didn't help. When I ran machine at the rated processor speed it would freeze up during render, so I had to 'underclock' down to 1.35 ghz from the 1.8 my 2200+ AMD is rated for. That led me to a discussion on AMD's forums, and I ddiscovered that I need to regularly blow the dust from the inside of my CPU's heatsink, or it will turn the heat sink into an insulator and raise my CPU's temperature above tolerance. When running Vue on 1.8ghz, I had reached 75.5 degrees Celsius when I should be in the 40s. That doesn't solve the memory issue, but it helps with crashes that come about when the memory issue gets really up there.

Truth has no value without backing by unfounded belief.
