Text animation, anti aliasing screwing things up

mc_ourWork.addEventListener(MouseEvent.MOUSE_OVER, ourWorkOver)



function ourWorkOver(event:MouseEvent):void
{
	TweenMax.to(mc_ourWork, .2, {tint:0xFF3399});
}

That screws up the anti-Aliasing on the text, why is this? Is their any fix for it (other than selecting anti-aliasing for animation)

It either messes up the anti-aliasing or it cuts off a piece of the text
