Totally non-responsive to keyboard presses - actionscript-3

Question

This doesn't respond to pressing Enter -traces give no results.
Is there any way to do this that works?
This is just extra ridiculous writing to get past the ludicrous posting restrictions.
Yaddah.

This code part in
Board.as- appears to work.
function kill (e2:KeyboardEvent):void
{if (e2.keyCode == Keyboard.NUMBER_1)
{removeChild(this.startBox);
startBox = null;
}
else if (e2.keyCode == Keyboard.NUMBER_2)
{removeChild(this.startBox);
startBox = null;
}
else if (e2.keyCode == Keyboard.NUMBER_3)
{removeChild(this.startBox);
startBox = null;
}
else if (e2.keyCode == Keyboard.NUMBER_4)
{removeChild(this.startBox);
startBox = null;
}
else if (e2.keyCode == Keyboard.NUMBER_5)
{removeChild(startBox);
startBox = null; }
else if (e2.keyCode == Keyboard.NUMBER_6)
{ removeChild(this.board.startBox);
startBox = null;}
else if (e2.keyCode == Keyboard.ENTER)
{removeChild(startBox);
startBox = null;}
Maybe I've give up on keyboard for this part and use mouse events instead- in a previous structure I couldn't have done that as mouse was already occupied doing something but that should be freed up now.
By the way this isn't need on stage initialisation.

Answer 1

Your sprite will never receive any KeyboardEvent. You should add your event listeners directly to the stage. Of course, you have to obtain a link to the stage.
In your constructor delete
this.addEventListener(KeyboardEvent.KEY_DOWN, myKeyDown2);
And add the following:
//Your constructor
...
if(stage)
initKeyboardEvents();
else
addEventListener(Event.ADDED_TO_STAGE, initKeyboardEvents)
//End of constructor
...
//New function
private function initKeyboardEvents(e:Event = null):void
{
stage.addEventListener(KeyboardEvent.KEY_DOWN, myKeyDown2);
}
