-Fix: For everyone who tried to crash the game by opening a huge amount of windows and stickying all of them; bad luck. It's fixed now (thanks Tron for the helpful criticism). First all normal windows are a candidate for replacement, then if none are found, sticky windows. Then..well that should not happen :)
