So far there is no way to my knowledge they can detect windower, however you must know that the windower has been out for a little while now, and they didnt give a crap about it before it start implimenting how much shadows you have or how much % of HP the mob has or how much TP everyone in your party has. Having the displays and add-ons is what makes it illegal now, not the windowing out function. I use one, but only to window out and i disabled the TP and HP% thing. I just wanna window, i dont agree with the add-ons as much.
