onMouseMove?

Hello everyone.

I am using the following code in order to create an effect when the mouse moves:

var count = 0;

_root.onMouseMove = function()
{

    _root.attachMovie("MCTween", "MCTween" + count, count);
    _root["MCTween" + count]._x = _xmouse;
    _root["MCTween" + count]._y = _ymouse;
    _root["MCTween" + count]._rotation = Math.round(Math.random() * 70);
    count++
}

_root.onMouse

I would also like to do that when the mouse cursor is still. Is this possible?
Thanks in advance.
