After update kde4.0.4 to 4.0.8* shortcut_keys not working...

I just update my system “openSuSe11” by onclick install to the newer KDE4 available , everything its looking great so far but , here comes the “but” my shortcut keys , that I previous edit using “kde menu editor” are not working any more .... they are there still configured , the keyboard seems to be working
properly but no action when I press the keys (“home”,”favorites”, “calc”and soh on) ... I already set and reset a dozen times but nothing happens ...
pls help me launch firefox by pressing just one key ...


any ideas ...
