Hi Stefan,

I can hardly believe that "producing input screen" is a candidate for reasonable use case at all! As far as I can understand, you are trying to introduce a constraint that use case can be associated only to its primary actor. I find this completely wrong with respect to real use case concepts. Moreover, just try to imagine with how many use cases would you and up (if you ended up at all) modeling a real world application.....I bet for a hudge number.
