Text scroller + mouseover stop?!

1

I made a news scroller with dynamic read function… but is there anyway to make a on mouseover and stop function to this thing?

here is the action on 3 frames…

frame 1


pos = 90;

frame 2


pos = pos-1;
_parent.news._y = pos;
if (_parent.news._y<=-320) {
	gotoAndPlay(1);
}

frame 3


gotoAndPlay (2);
