In kineticjs I am creating dynamic rectangles that are draggable. However when I create a new rectangle, the rectangle behind it automatically drags. I dont want this to happen.
You can see the behaviour in demo at http://jsfiddle.net/sandeepy02/8kGVD/12/
Step 1: Choose "create rectangle" and create rectangles. Step 2: Choose "Move rectangle" and move the rectangles. Step 3: Choose "create rectangle" and create rectangles. This causes the rectangles previously created to also move. This is unwanted.
