Hi Guys,
            spotted this late last night and didnt get a chance to file a bug on it, writing this note so I dont forget completely.
Was playing with the node tool and found that there seems to be an indexing error (looks like an off by one type of thing)
where whenever you do click to add nodes or try to drag the curve it does it to the wrong line segment. 
so if you have
A-----B-----C
and double click between A&B you get a node between B&C
likewise if you try to drag to reshape it moves BC instead of AB.
 
Cheers
 
John
