Mouse buttons stopped working

[dgrey]

It all started with an AVI I played off the web. The avi kept looping and I couldn't shut it down, nor the machine. Had to power off.

Now, the mouse buttons do not work. Mouse moves around, but pressing the buttons does nothing. However, hit ctl+alt+del and you get the selection screen for shutdown etc, and it works there. I have the exact same symptoms with an external mouse so it's not the trackpoint buttons.

Everything also works in safe mode, I just can't figure out what would cause this.

This is on a T60WS running XP SP2 with all appropriate patches.

Anyone?
