with the new boot camp release i installed it on my MBP. I had XP on it prior and i did a clean install of vista. when i'm using my MBP in Vista it just shuts off and i hear the start up chime and look like it will boot again to vista but nothing happens. then i have to hold to power button down and restart. during reboot it goes to the windows was not shut down properly screen. is anyone else having this problem... this did not happen under xp even when i was playing games on it.
