Playback doesn't play when you hit the spacebar but work with a spacebar and then mouse click. I am not sure if this is a gimmick but it makes life difficult. other playbacks seems to work just fine Adam
This sounds like what I am experiencing as well. I already filed a bug for it (bug #384151). Can you check and see if this is the same thing you are running into?
