Alex,
The change you made worked for the case where the function is assigned to a
variable, but it doesn't account for the function being passed as an
argument to a function.
This still doesn't work for me:
this.addEventListener("mousedown", this.simpleButton_mousedownHandler);
However, as a workaround, I can do this, for now:
var mouseDownListener:Function = this.simpleButton_mousedownHandler;
this.addEventListener("mousedown", mouseDownListener);
