hitTest trouble

Hey there!
I’m messing around with the following code:

onEnterFrame = function() {
        speed = 6;
        if (_root.fakeHit.hitTest( _root._xmouse, _root._ymouse, true)) {
                _root.bar01._y += ((_root._ymouse-_root.bar01._y)/speed);
                
        }
}

When you rollOver or enter the movieclip “fakeHit”, the movieclip “bar01” starts to move, simple enough. But when you rollOut the movement stops imidetly!? Why is that, and is there a way to make the movement ease out when rolling out the hit area?
