This has happened before. It seems to only happen when I'm editing my User Notes. I have BetterTouchTool running. My thumb will brush the lower left corner of my Magic Track Pad, and abracadabra! The ID windows start piling up. The most I've had is three. After that, they decrease one at a time down to none, then back up to three, etc..
