You can still get into that mode by using ctrl-alt. There's an interesting usability question here. What keys should be passed to the guest? Should alt-tab be passed? Should num-lock/caps-lock be passed? It would be pretty easy to hack up a patch that grabbed the keyboard on mouse in and released it on mouse out in grabless mode. The only question in my mind is would this be acceptable from the users perspective? Regards, Anthony Liguori > Unrelated, I also have a general USB issue which makes me almost not > use it.
