Idk if this should be in Report a Bug or Feedback, but I'll just put it here.
Now I'm not a professional coder, so I don't know if there's a real difference between Windows & Mac clients, but I've never had this problem on my other pc, so I figured I'd put this here just in case.
Anti-AFK event doesn't show the actual keyboard in order to spell out the word, so I am forever trapped (or just restart client, I know).
