--- Comment #2 from Ben Anderson roothorick@new.rr.com 2009-05-12 02:39:20 --- This has nothing to do with WMs. It happens if the WM is forbidden from controlling the windows, it happens on an X server where no WM is running, and as you would already know if you had bothered to read my description, it even happens when the application is running inside a virtual desktop. (For the record, I've tested all three with the same result -- frozen fullscreen app on top of unclickable window.)
