1. I open an application e.g. terminal
2. I close the application's window
3. Keyboard shortcuts do not work at all and if I want them back working, I have to click on the desktop's background
I bet it has something to do with focus or compiz settings, because I've already had some problems with those in Unity. Now I'm on the "classic" ubuntu desktop. It didn't happen before upgrade.. Please help me. This is very inconveniant.
