Key.getCode() not returning anything for Enter key

1

I’m using following code to trap the key press events.
[AS]
myListener = new Object ();
myListener.onKeyDown = function ()
{
trace(Key.getCode());
if (Key.getCode()==13)//code for ENTER key is 13
{
trace (“asdf”);
}
};
Key.addListener (myListener);
[/AS]

Now when I hit ENTER nothing is traced and “asdf” isn’t printed,
while hitting anyother key gives it’s code in output.

Any clue?
