The "A" key only registers on the first KEY_DOWN instance on no subsequent instances

Here you go, the most primitive code in the entire world:

private function init()

                    {

                              trace('balls');

                              stage.addEventListener(KeyboardEvent.KEY_DOWN, kDown);

                              stage.addEventListener(KeyboardEvent.KEY_UP, kUp);

                    }

                    private function kDown(e:KeyboardEvent)

                    {

                              var targ = e.keyCode;

                              trace(targ);

                    }

                    private function kUp(e:KeyboardEvent)

                    {

                              var  targ = e.keyCode;

                              trace(targ);

                    }

all keys trace but my "A" key, the "A" key traces the first time and never again.
