quirk or standard mode

[David Graham]

Hi
I used to be able to type the line below into the address bar of a browser
(Opera but works in IE I think)
javascript:alert(document.compactMode);
and it would tell me if the browser was in quirks mode or standard mode.
They all come back as Undefined at the moment.
Anyone know why?
thanks
David

There's a typo. It's document.compatMode
