Hmm -- I guess I never added EVT_FC_MOTION, because I didn't think anyone
would want a mothnion event bound to an object -- they do have ENTER and
LEAVE events.
But I suppose if you have a large object, you may want to catch Motion
events on it....
So the problem is that the Mouse GUIMode isn't doing teh right thing with
passing the event on teh the HitTest code...
Looking at that now.
