I am not crashing as much as I used too, I am however crashing in a different way. Previously I pretty much only crashed at the start of the battles. Now I crash mid game with no real reason for it. This change occured when I moved from vista to win 7. But I am crashing less (but still too much prob 1/10 ish games where as it used to be 1/5).
I actually can't remember the last start of battle crash I had, which I guess is a good thing.
