Christoph Oelckers 3046a7dd81 - be more thorough with 'in menu' checks for certain protected functions. 
They would also pass the test if a menu just was open but not the actual invoker.
Also error out if this happens so that modders can see that they are doing unsupported things. Silent failure is not a good idea here.
