Delete onMouseMove problem

Hi all,

I am working on a drawing application in as2. I m drawing on a movieclip called canvas_mc.

My problem is when i draw a rectangle. And on OnMouseUp i delete the OnMouseMove event.

And then i check for the mouse hitTest with this rectangle. But it dont show me the hitTest when i MouseOver on the Rectangle because i have deleted the onMouseMove Event.

How can i overcome this problem. Please Help… this is very urgent for me.

Thanks
Pavan
