[flexcoders] Glow Effect Sticking around

[richmcgillicuddy]

I have a glow effect, that I place on a button (See source below) -
once completed, my button stays 'glowing' even after I invalidate the
button. Any ideas?

 private function onGlowEnd(event: Event) {
                btnDrop.invalidateDisplayList();
          }
          private function onBtnDropClick(): void {
                var myGlowFilter : Glow = new Glow(btnDrop);
                myGlowFilter.color = 0x00FFFF;
                myGlowFilter.blurXFrom = 10;
                myGlowFilter.blurYFrom = 10;
                myGlowFilter.blurXTo = 0;
                myGlowFilter.blurYTo = 0;
                
                myGlowFilter.alphaFrom = 0;
                myGlowFilter.alphaTo   = 1;
                myGlowFilter.duration = 3500;
                myGlowFilter.strength = 25;
                myGlowFilter.addEventListener(EffectEvent.EFFECT_END, 
onGlowEnd);
                myGlowFilter.play();    
          }
