Windows Vista hanging solution

I had problems with Vista and SEV hanging on the last part of updating a turn. I played around with it for a while and found that I was able to continue the game by setting the processor affinity to a single processor. I also upped the priority of the process one level. I have attached links to show how it is done.

I also find this site has some good ideas.
