Well, it's not really a "problem", but I'm curious about this.
My mouse (it's the one with the 'laser' not the ball under it) just suddenly stopped working yesterday. I thought my PC froze at first, but everything was fine, it was just my cursor that wasn't moving at all. I re-started my PC twice, and no effect. I'm just wondering what could have happened to it? The laser is still working and all, it's just that when I plug in the mouse, no movement from the cursor.
