AS3 scale and alpha tweening

Hi all, I have this file working just as I want it, except there's one annoying little problem. When you move the mouse over the lettering in one of the boxes then move your mouse away it appears again! http://www.andrewsaldridgehost.com/error/flashMapAS3Test.swf - The FLA is here: http://www.andrewsaldridgehost.com/error/flashMapAS3Test.fla and here's the code:
import fl.transitions.Tween; 
import fl.transitions.TweenEvent; 
import fl.transitions.easing.*; 
import flash.events.* 

button_mc.addEventListener(MouseEvent.MOUSE_OVER, grow) 
button_mc.addEventListener(MouseEvent.MOUSE_OUT, shrink)
button_2_mc.addEventListener(MouseEvent.MOUSE_OVER, grow)
button_2_mc.addEventListener(MouseEvent.MOUSE_OUT, shrink)

function grow(e:MouseEvent):void { 
    
	var sX:Tween = new Tween(e.currentTarget, "scaleX", Regular.easeOut, e.currentTarget.scaleX, 1.5, 0.5, true) 
    var sY:Tween = new Tween(e.currentTarget, "scaleY", Regular.easeOut, e.currentTarget.scaleY, 1.5, 0.5, true)
	var area:Tween = new Tween(e.currentTarget.getChildAt(1),"alpha",Regular.easeInOut,e.currentTarget.getChildAt(1).alpha,1,.4,true);
	
} 

function shrink(e:MouseEvent):void { 
     
    var sX:Tween = new Tween(e.currentTarget, "scaleX", Regular.easeOut, e.currentTarget.scaleX, 1, 0.5, true) 
    var sY:Tween = new Tween(e.currentTarget, "scaleY", Regular.easeOut, e.currentTarget.scaleY, 1, 0.5, true)
	var area:Tween = new Tween(e.currentTarget.getChildAt(1),"alpha",Regular.easeInOut,e.currentTarget.getChildAt(1).alpha,0,.2,true);
	
}

Looks like the mouse over event is being called when its shrinking as well, one way to stop this would be to remove the event listeners on that button when its in transition. See the code snippit for how to do this.

import fl.transitions.Tween; 
import fl.transitions.TweenEvent; 
import fl.transitions.easing.*; 
import flash.events.* 

button_mc.addEventListener(MouseEvent.MOUSE_OVER, grow) 
button_mc.addEventListener(MouseEvent.MOUSE_OUT, shrink)
button_2_mc.addEventListener(MouseEvent.MOUSE_OVER, grow)
button_2_mc.addEventListener(MouseEvent.MOUSE_OUT, shrink)

function grow(e:MouseEvent):void { 
    //Remove listeners
	e.currentTarget.removeEventListener(MouseEvent.MOUSE_OVER, grow);
	e.currentTarget.removeEventListener(MouseEvent.MOUSE_OUT, shrink);
	
	
	var sX:Tween = new Tween(e.currentTarget, "scaleX", Regular.easeOut, e.currentTarget.scaleX, 1.5, 0.5, true) 
    var sY:Tween = new Tween(e.currentTarget, "scaleY", Regular.easeOut, e.currentTarget.scaleY, 1.5, 0.5, true)
	var area:Tween = new Tween(e.currentTarget.getChildAt(1),"alpha",Regular.easeInOut,e.currentTarget.getChildAt(1).alpha,1,.4,true);
	
	//using sX as a target as it an sY are the longest tweens
	sX.addEventListener(TweenEvent.MOTION_FINISH, enableListeners);
} 

function shrink(e:MouseEvent):void { 
    //Remove listeners
	e.currentTarget.removeEventListener(MouseEvent.MOUSE_OVER, grow);
	e.currentTarget.removeEventListener(MouseEvent.MOUSE_OUT, shrink);
     
    var sX:Tween = new Tween(e.currentTarget, "scaleX", Regular.easeOut, e.currentTarget.scaleX, 1, 0.5, true) 
    var sY:Tween = new Tween(e.currentTarget, "scaleY", Regular.easeOut, e.currentTarget.scaleY, 1, 0.5, true)
	var area:Tween = new Tween(e.currentTarget.getChildAt(1),"alpha",Regular.easeInOut,e.currentTarget.getChildAt(1).alpha,0,.2,true);
	
	//using sx as a target as it an sy are the longest tweens
	sX.addEventListener(TweenEvent.MOTION_FINISH, enableListeners);
}

function enableListeners(e:TweenEvent):void {
	//Clean up
	e.currentTarget.removeEventListener(TweenEvent.MOTION_FINISH, enableListeners);
	
	
	//Redefine Listeners based on the tween's target
	e.currentTarget.obj.addEventListener(MouseEvent.MOUSE_OVER, grow);
	e.currentTarget.obj.addEventListener(MouseEvent.MOUSE_OUT, shrink);
}

Oh and tweens have this nasty habbit of being cleaned up by the garbage collector before they complete, the trick to fixing this is to apply a listener to them then remove that listener when it completes. Have a look at http://www.flashmorgan.com/index.php/2007/11/18/as3-garbage-collection-the-reason-your-tweens-are-ending-early/ for more information on that issue :).

you need to incorporate an if statement to check a variable to see if the object is currently on the screen, and only run the tweek if it's visible... otherwise, flash will restart from the original variables of the clips you're modifying. I could give the exact code you may need, but I'm not at home right now, sorry. :(

Hi, you're the second one this week.
you need to set the mouseChildren properties to false

button_mc.mouseChildren = false;
button_2.mouseChildren = false;

the thing is the mc inside is triggering the mouse over etc as well

Thanks Blue Genie, I thought as much! When I didn't move the mouse over the text it was okay!!! Thanks for the other assistance though, it gave me a good insight into what I was doing :] Points for all!
