Comment 2 for bug 460572

I experienced something very similar. Toshiba NB200, fully pathed Karmic: FB consequently freeze (no pun intended) on exit: you can play for as long as you want, but once you hit Esc to end the game, the window freezes. If you are good, you can een register to the hall of fame, but that's it. No refresh, nothing. Not reacting on any mouse of keyboard action. Killing the process from the terminal helps. Funny thing is, identical config on Asus eee901 works flawlessly.
