hi
I asked some questions about how to implement custom behavior class. So far it almost can work well. But today I find new problem.

I define my own behavior class, then catch NodeModified event, Cancel event in my class. Also when user try to move a shape, my code will insert a tracker node, actually user operate this node to show where the user's node will be at. In most cases it can work well.

But if use just move 1 pixel, then Cancel event will be called. If move 3 pixel ore more NodeModified event will be called. That's why? and how to solve this problem?

Thanks a lot
