I reinstalled the game and patched it up. Windower XIV still works exactly the same as ever. I guess Squenix isn't going to take action against Windower XIV to block it's mechanism is the client, at least until they create a proper Fullscreen mode which doesn't crash when the client loses focus or they finally add a real Windowed Fullscreen mode. I don't care which really, they just need to fucking do something about how sad the client is in terms of being a Windows application.
I'm scared to actually log in and play it though. :|
