wmurpht: it takes a bit of finesse... I had to do it several times, but it does work. It shouldn't have anything to do with the latest image; but perhaps it is a problem with your hardware keys settings. Open a terminal and enter: Code: cp .xbindkeysrc.dist .xbindkeysrc This should copy the latest version of the hardware key bindings; it doesn't copy it automatically, in case you have custom keys mapped.
cp .xbindkeysrc.dist .xbindkeysrc
