.AS file Button difficulties

programming flash

[COLOR=#333333]Hello,

 I am new here. I am creating my website buttons and wanted to use a .AS file to control the mouse over and mouse out events for transparency. For some reason, it starts out as a lit button, but, once you roll over it, it then behaves as designed. To see the example, go to: http://www.kmanstudios.com/kmansite/

That is the test area for the site. I’m stumped. But, that’s not saying much really at this stage of my learning curve. When I used the base code on single buttons, it worked fine, but in the .AS file, it’s not quite right.
Thanks in advance!!

Here is the .AS file code I used.

package
{
import flash.display.MovieClip;
import fl.transitions.Tween;
import fl.transitions.easing.*;
import flash.events.MouseEvent;

public class Button extends MovieClip

{
    
    public function Button()
    {
        buttonMode = true;
        this.addEventListener(MouseEvent.MOUSE_OVER, FadeIn);
        this.addEventListener(MouseEvent.MOUSE_OUT, FadeOut);
        
        
    }
    
    private function FadeIn(event:MouseEvent):void
    {
        var inTween:Tween
        this.removeEventListener(MouseEvent.MOUSE_OVER, FadeIn);
        this.addEventListener(MouseEvent.MOUSE_OUT, FadeIn);
        inTween  = new Tween(this, "alpha", Strong.easeIn, 1, 0, 0.25, true);
        event.updateAfterEvent();
    }
    
    private function FadeOut(event:MouseEvent):void
    {
        var outTween:Tween
        this.removeEventListener(MouseEvent.MOUSE_OUT, FadeOut);
        this.addEventListener(MouseEvent.MOUSE_OVER, FadeOut);
        outTween = new Tween (this, "alpha", Strong.easeOut, 0, 1, 0.25, true);
        event.updateAfterEvent();
    }
}
