Minor Description
A few strange things happen when I attempt to drag a relationship from an entity on the graph to another.
1) If I move my mouse over a processor/processor group/funnel/input port and see the (->+) to create a new relationship icon, then mouse down on it, the mouse down action causes the icon to move down about 10 pixels. I don't know why this causes the icon to move.
2) If I do a mouse up before dragging the mouse pointer off the processor, then the new relationship icon goes away, and I cannot get it to return unless I move my mouse off of the processor and back onto it again. I would expect the icon to come back without having to move my mouse off the processor
3) If I do click and drag a relationship from one processor to another the (->+) new relationship icon gets dragged along. Is this intentional? It does not seem necessary to me.
