Hi,

I would very much like to do so, but unfortunately don't get what  
you're heading for. NSView does not provide any means to switch  
autoscrolling on and off, therefore I added this functionality to  
ChlorMainView. GrabHandTool switches then between autoscrolling and  
non-autoscrolling in the activate: and deactivate: methods. What else  
should be moved into these methods?

Thanks for your patience,
	Flo
