Comment 21 for bug 1041874

The issue I am having might be similar. On the Dell XPS 13 there is a click pad where the touchpad covers the physical buttons.

When I set AreaBottomEdge to the correct value, moving one finger into that zone doesn't move the pointer, so far so good.

BUT if I rest my finger on the physical left button (left hand), which is inside the dead zone, that finger is still registered by the driver and taken into account as a multitouch gesture: if I move another finger (right hand) in the live zone up and down, it will scroll up/down (because I have the two finger scroll enabled). Disabling two finger scrolling doesn't help, the second finger (right hand) cannot move the pointer.

This is annoying because I was used to have physical buttons on my old laptop and always had a finger resting on the button.

One possible fix for this would be to make the AreaBottomEdge / dead zone really dead, which means that any finger touch/rest inside that zone must be completely ignored.

What do you think ?
