Forums Bug Reports some @windownames forbidden while using /window?

it seems that @desktop and @mirc are wrong names to open/manipulate a custom window..

eg.

or


(and maybe some other window names..)
give error msg:
* /window: invalid parameters

(thnx to Zerg/merci à Zerg)

I tried @mIRC once and yep, it didn't work. I think this is intentional though.

You also can't use @mdi :)
