Mose Over/Out Issue

Question

I have a script that will expand a box on  a mouse over of a button, and shrink it on a mouse out of that button. It seems to have a problem. Most of the time its works fine, but on occasion it will tween out to 100% , and then I need to move in and out to get it to sync back up. Here is the script. it seems to happen If i move over or out of the button, while its tweening
Hopefully someone can help me find the bug
import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;
select_mc.addEventListener(MouseEvent.MOUSE_OVER, expandonepad)
setChildIndex(pad_mc, 1)
setChildIndex(select_mc, 0)
pad_mc.scaleY=0
pad_mc.scaleX=0
var growpadx:Tween
var growpady:Tween
addChild(pad_mc)
function expandonepad (Event:MouseEvent)
pad_mc.x=45
pad_mc.y=20.00
growpadx=new Tween (pad_mc, "scaleX", Strong.easeOut, pad_mc.scaleX, 1.02, 2, true)
growpady=new Tween (pad_mc, "scaleY", Strong.easeOut, pad_mc.scaleY, 1.05, 2, true)
select_mc.removeEventListener(MouseEvent.MOUSE_OVER, expandonepad)
select_mc.addEventListener(MouseEvent.MOUSE_OUT, shrinkonepad)
function shrinkonepad (Event:MouseEvent)
growpadx=new Tween (pad_mc, "scaleX", Strong.easeIn, pad_mc.scaleX, 0, 1, true)
growpady=new Tween (pad_mc, "scaleY", Strong.easeIn, pad_mc.scaleY, 0, 1, true)
select_mc.addEventListener(MouseEvent.MOUSE_OVER, expandonepad)
select_mc.removeEventListener(MouseEvent.MOUSE_OUT, shrinkonepad)

One approach that might work would be to stop the Tween before you start another, but you'll need to test for the Tween before you try...as in...
function expandonepad (Event:MouseEvent)
      if(growpadx){
          growpadx.stop();
          growpady.stop();
