whenever i shutdown the computer it says windows is shutting down, then i see the light on the mouse turn off but the computer stays on for about 10-20 min after. i just reinstalled windows so its not that - this problem also happened before i reinstalled. i havnt installed anything yet besideds drivers, itunes and quicktime. the only thing i can think of is that when i was installing the windows and it was copying the setup files it said cannot copy pro_seg1.swf so i skipped it. this happened on my last instalation of windows too.
