Public bug reported:
This problem only seems to occur on my desktop where I have an Apple
Trackpad, the multi-touch synaptic trackpads in both of my laptops, a
Lenovo T410s and an HP dm1z, do not seem to cause this hang. I can use
two fingers, which now seems to act as a middle-click, but if I try and
use a third finger, everything hangs except the mouse pointer. I can get
the mouse pointer to also hang for short periods by using more then 2
fingers on the trackpad in some long term fashion.
