When clicking in the SVG document, a small mouse movement will be interpreted as a drag action.
Solution : start dragging only after the mouse has moved a minimum distance.
Good to know you've acknowledged this problem. Was about to open a ticket about it. Yes a minimum threshold would be wonderful. But the question then becomes -- what is an acceptable threshold?
I I could avoid this problem by removing the code "u.drag (A.clientX-g, A.clientY-e);" do not think it optimally but it was useful for something particular.
@matiascano Of course, removing the "drag" feature removes the problem :-)
Added a 5-pixel threshold.
