Make function inactive at scale==x

Question

i have some movie clips that when moused over, become visible.  when clicked the clips are clicked on they tween to center-stage and zoom to fill the extent of my stage.
one the zoom completes, i'd like the mouse over effect and function to no longer be active.
i've been trying this by just making the mc invisible at scaleX>1.  This does not do the trick...
if (allthings.NEZOOM.scaleX>1{
     allthings.NEZOOM.alpha=0
the function that is running the MOUSE_OVER is called NEOVER and looks like this
function NEOVER(e:MouseEvent):void{
    TweenLite.to(allview.allthings.NEZOOM, .5, {autoAlpha:.5,overwrite:true});
    TweenLite.to(allview.allthings.NETXT, .5, {autoAlpha:.85,overwrite:true});
is there a way I could make NEOVER inactive after once i click on the NEZOOM movielip?  the click event looks like this
function NECLK(e:MouseEvent):void{
var calledx:Number;
calledx=(allview.allthings.NEZOOM.x);
var calledy:Number;
calledy=(allview.allthings.NEZOOM.y);
var goto:Point=new Point(156-calledx,246-calledy);
//TweenLite.to(allview.allthings,.5,{x:goto.x,y:goto.y,onComplete:NEZM});
TweenLite.to(allview.allthings,.5,{x:goto.x,y:goto.y,scaleX:1.5,scaleY:1.5});
TweenLite.to(allview.allthings.hydro, .5, {autoAlpha:1,overwrite:true});
thanks in advance

Answer 1

intersting...
so i've tried to include the mouseEnabled piece into the if statement.
when i click on the mc (NEZOOM), the parent (allthings) scales causing everything to appear larger
if (allthings.scaleX>1){
                allthings.NEZOOM.alpha=0;
                allthings.NEZOOM.mouseEnabled=false;
i've tried the if statement above and the mc is still active when the parent scaleX > 1.  am i missing something obvious?
thanks
