I don't know if this is the same, but suddenly my slate starting acting as if a ghost was randomly tapping the screen, pinch zooming in and out and holding down the touch long enough to cause right clicks. I was in IE9 at the time and it was quite the show. I quickly slept the slate then woke it up which seems to have reset the problem. It happened three times over an hour. I'm in the prairies right now and wearing a thick nylon 'wool' lined vest(it's cold here) and I wonder if that's causing the problem. I hadthe slate pressed right on the wool part of the vest when this started, and it's fairly dry here. Hasn't happened again since though.
