Hi  
I am just trying to understand the scope of [COLOR=“Blue”]this[/COLOR] in AS3 for example in AS2

> basicM\_btn.onRelease = function() {  
> this.\_visible = false;  
> }

Would hvae made the button invisible

In AS3 I was expecting to write the same thing as this

> function clickHandler(event:MouseEvent):void {

this.visible = false;

}

menuA\_btn.addEventListener(MouseEvent.CLICK, clickHandler);

However this sets all of the content on the stage to visible = false

Is there a difference in the way that [COLOR=“blue”]this [/COLOR]works in AS3

Thanks for your help
