No I don't...your post on the CPU utilization helped but I noticed once I get booted it happens more and more....and when I go from the hanger to the runway it will boot me as soon as the engines fire.If I reboot It helps for a while. I can fly planes all day long. My old system was the same way only worse and I had an old 400mhz gateway with 192 meg. The new system is a dell with 2.4mhz and 256 ram. I had norton utilities on the old one and would run it and it would find lost chains and the like, I would save those to files and I could fly a bomber from 10 min to 2 hours before it would start all over again. With this new one I don't have Norton utilities on it so I don't know whats happening.
It is weird I do know that. Also when it's acting up just by changing views will boot me, but it's also just happened flyin in auto pilot.
