Actually, I am using a TrackballManipulator and replacing its ref_ptr with a new NodeTrackerManupulator when I have to enter "node tracking mode". I'm not using the KeySwitchMatrixManipulator, but simply changing back and forth, overwriting the ref_ptr... Maybe sometimes I get one handler and sometimes the other? It shouldn't be the case...
