Comment 10 for bug 839769

Yes I think the reports do need separating again.
The author of the other bug has clearly stated the problem affects click pads (such as on Macbooks/Airbooks) where the entire touchpad clicks whereas this one is affecting TAPS on regular, non-clicking touchpads.

But as the previous poster mentioned, not only is this bug affecting functionality of other applications running in unity, it is affecting functionality of unity itself which seems to make the whole situation all the more odd.
