Comment 6 for bug 998056

As an added note, I agree that this appears to happen about 90% of the time when I'm connected to my laptop dock at work with 2 screens attached. But when working off the dock at home on the laptop screen only, it happens far less often, maybe only about 50% of the time. Still extremely disruptive.
