Problem with Keys

I was trying to move my ship based on WASD and find out that A and S were not working, them i get this code from the flash help itself:


function reportKeyDown(event:KeyboardEvent):void
{
    trace("Key Pressed: " + String.fromCharCode(event.charCode) +         " (character code: " + event.charCode + ")");
}
stage.addEventListener(KeyboardEvent.KEY_DOWN, reportKeyDown);

And notice that it traces nothing when i press a or s, only when i press wd
This happens with some other Keys too
So, how can i solve that?It was working in f9 alpha…:m:
