Pełen ekran-problem z KeyListenerem

Witam.
Zaczynam sie uczyc pisać aplikacje pełnoekranowe. Czy moze mi ktoś powiedzieć dlaczego nie "widzi" wciskania klawiszy?

Pomysły by ignorować błędy

catch(Exception e){
}

oraz nadawać swoim klasom (Frame i Panel) nazwy takie jak mają standardowe klasy Javy są raczej głupie.
Żeby komponent reagował na klawiaturę musi mieć fokus, na JPanel domyślnie fokus się nie przenosi.

    public Panel()
    {
        setFocusable(true);
        create();
    }
