Key problem with 4.10

[WhiteSnake]

Its not related to that at all, the "`" and "=" are changed sudenly mid game to "Kanji" and "@", thats the problem here.

Wen i type in chat they apear normal, but wen i enter the Controles configuration In Game, and try to Reset the Key they apear Wrong as "Kanji" and "@"

I want to know Why/How this is posible from working fine like normal, to no longer working in the middle of a game, and how to fix/prevent this from happening.

(p.s. if i change my Languadge setting for the Keyboard from US-International to Nederlands (Dutch) the "`" key changes to "@" and the "=" to "°")
