A friend has a Lenovo G580 laptop which I recently upgraded to Windows 8, along with the official Touchpad drivers from Lenovo.

Now since its one of the new machines, the touchpad supports Windows 8 specific gestures.

One of these gestures is that whenever you swipe from outside the right hand side of the touchpad, the Charms bar is activated in Windows. Now whether it is due to incorrect or sloppy drivers from Lenovo, this gesture is far too sensitive and the charms bar pops up every time the finger reaches the right hand side of the touchpad.

The friend wants me to disable this charms bar from popping up due to the touchpad gesture.

What are my options & what all can I try?
