[flexcoders] Question about "mouseMove"

[Prasad Dhananjaya]

Hi,

I have a small question about mouseMove action.

Below code draws an arrow between mouseDown point and mouseUp point.
It works well. But arrow displays only after mouseUp event.I want to
display arrow during moving of mouse (before I do mouseUp). 
I think I have to add "something" to mouseMoveHandler().
But didn't know what? Can someone tell me how can I do this?

Thanks,
