And of course I can sit a day and configure the css … may be it will get better. And of course I can sit another day, when the next update apperars. And of course i can write my own menus and just inject them for different screen sizes. But the point is: There was a working version of the menu. And all of the versions are based on the latest WP-Version – so there is no question that the problems are weaver problems.
And of course there is no need that weaver solves my problem. As i said, I’ve chosen the wrong software. But – who could have thought, that a developer replaces a working function with a not working function oder just deletes a working function.
