So I've been following this Flash book and it suggested for me to try my own functions to trace my mouse activity on buttons. E.g.

stop()

function buttonDoubleClick(myevent:MouseEvent):void{
trace("You Double Clicked Me"
}

myBtn*.addEventListener(MouseEvent.DOUBLE_CLICK,buttonDoubleClick);

*name of the button instance

<> The problem is that the trace window doesn't show up and tell the "You Double Clicked Me" thingy after you click a button instance myBtn.Others like ROLL_OVER , MOUSE_OUT and CLICK work with trace function.Any suggestions , maybe the book writers problem?
