Sorry if i'm being simple here, done a bit of flash graphical
work but trying to make the transition to coded, so probbally a
complete noob mistake.

:- homepage_mc which is a movieclip on my main stage. Fades in Fine
on startup, but when the button mybuttons.homebutt is pressed i get
no response.
Any help greatly appreciated.

I have a problem that is related to this thread. The
following code works but the results are unpredictable. Also when i
try it in CS4 it works but in CS3 it doesn't work. Can someone take
a look at it and tell me what's wrong.
package{
import flash.display.MovieClip;
import flash.events.MouseEvent;
import fl.transitions.Tween;
import fl.transitions.easing.*;
public class Motion extends MovieClip{
public function Motion(){
this.addEventListener(MouseEvent.MOUSE_OVER,over);
this.addEventListener(MouseEvent.MOUSE_OUT,out);
private function over(event:MouseEvent):void
var myTweenX:Tween = new Tween(this, "width", Strong.easeOut,
100, 150, 5, true);
var myTweenY:Tween = new Tween(this, "height",
Strong.easeOut, 100, 150, 5, true);
private function out(event:MouseEvent):void
var myTweenX:Tween = new Tween(this, "width", Strong.easeOut,
150, 50, .25, true);
var myTweenY:Tween = new Tween(this, "height",
Strong.easeOut, 150, 50, .25, true);
}
