Right! I suspected this but didn't know it for a fact, thank you. I just recently upgraded my Adobe stuff so it would play well with my computer. I had CS4 running on a machine 5 years newer and I wasn't getting the performance I thought I should be. Now that I've upgraded I can re-start some of those old multi-layer high-resolution projects I was stalled on...
