As of last night, the scroll wheel on my Dell/Alienware TactX mouse isn't working. Niether in freewheel mode or in the stepped/clicky mode. This couldn't be a driver issue right? The middle click and side scrolling do work. Reboot and un-plugging/re-plugging in the mouse hasn't worked either.

I'm on the AW 14, btw. I've had the mouse only 4 days now.
