Not able to use anything regarding creäting text.

            After typing in a sign, I'm not able to use anything regarding creäting or editing text, such as book and quills, signs, hanging signs, or the chat menu. When I close and reöpen the world, I'm still not able to use any of the aforementioned forms of communication, so I'm certain it's not a problem with my computer beïng able to run the game, especially after I've been able to use signs and books in past versions.
