Update of /cvs/fresco/Fresco/Berlin/src
In directory purcel:/tmp/cvs-serv8580/Berlin/src

Modified Files:
	PositionalFocus.cc 
Log Message:
Fix by cinap_lenrek (at gmx dot de):
"here seems also a problem in the PositionalFocus implementation. if here
goes wrong by dispatching the event to a controllear (wich is dead),
the controller will not be removed by the PositionalFocus and the
EventManager handels the exception as a scene graph corruption..."
