Bug Description

It is a usual behaviour when you rest your finger on left button area(not clicking it) and move cursor with your index finger.
Unfortunately it doesn't work.

evtest and xev reports contain attempt to move cursor while resting finger on the left button area.

Sorry for my english :)

I think what is needed is to set the property "AreaBottomEdge" to some value so that the lower portion of the touchpad surface is disabled with regard to mouse pointer movement.

I tried my suggestion and while I figured out that 1800 is the correct value, this bug remains.
