I believe i stated in the first line of my post that this is an Issue with ATI's driver's. I was simply attempting to expain why it was the JavaVM and not most windows apps that cause this issue. Quite frankly neither Sun nor ATI seems to show much proficency in writing windows Applications for their repsective products. ATI should prevent the reboot when it receives bad data, Sun should improve their writing for windows (alpha transparency is another example of these sort of problems).
