There’s a specific spot on my desk where I believe there's some radio interference that generates touch events on my Playbook. Note: Bluetooth and Wireless connections are disabled on the device during this test. I *think* that it's radio interference but I have no idea. It's something that only happens at one specific location on my desk so I'm a little confused. Initially I thought that the device was being hacked, but when I turned off all the connections and moved it around it became more obvious that this was a localized phenomenon.
