Jerky mouseOver/mouseOut

1

I’m doing a simple mouseOver/mouseOut function,
but it keeps being jerky in it’s animation, it is as if
the mouseover and mouseout collide randomly.
is there a better way to to this?

code below.

hotspot01.addEventListener(MouseEvent.MOUSE_OVER, hotspotOver, false, 0, true);

function hotspotOver(e:Event)
{
    hotspot01.gotoAndPlay(2);
}

hotspot01.addEventListener(MouseEvent.MOUSE_OUT, hotspotOut, false, 0, true);

function hotspotOut(e:Event)
{
    hotspot01.gotoAndPlay(8);
}
