Removing the localstore.rdf file solves the problem, but in my case it's not related to an upgrade. When I apply the fix, the problem reappears after a while. Right now it happens about 2-3 times a week. It can also be different windows that have the problem, sometimes it's the main window, sometimes it's the write mail window.
I'm working on a laptop with the second monitor changing often with different resolutions. Sometimes I have the impression that restoring the TB window on a screen that is different (smaller?) then the one where it used to be results in the full screen behaviour.
