Starting to lose interest in the whole game...

I think you're very fortunate that you're only "starting" at this point.

Just take a quick look over at the beta forum (XIV) and check out how many screenshots of XI players with there characters on display while running windower, right under the nose of SE..

If SE banned people who used Windower the game would die in no time, because on top of every other problem people are leaving for, they would be instantly removing a great deal of their PC players.
