Thanks Michael's - All seems logical for now. I suppose I am comparing curve editing with the likes of Corel / Illustrator where you have fine control. This obviously only works with nodes being on the bezier curve. As Moi has control nodes off the curve I suppose this has limitations for picking a single point on a curve and turning it into a corner?
