Clicking on the buttons lets the page scroll smooth to the bottom. The button there lets the site snap back to the top.
It supposed to scroll smooth to the top an the navigation buttons have to give the linked page.
In the rest of the pages I removed the action and the navigation there lead to the linked pages.
SmoothScroll does not work on map areas, only anchor (link) elements. Your back to top button is not a normal rectangular image, so it has been given a map area by Freeway*, and this keeps the Action from doing its thing. To fix this, click once on the button in your layout, choose Item / Export from the main menu, and save the image as a GIF or PNG somewhere in your Media folder. Re-import it into a pass-through box in place of the original button, and re-apply your link to that box. This forces Freeway to make a normal link instead of using a map area that only respects the circular button area.

I couldn’t have figured that out by myself. As you mentioned, the other buttons also are non-rectangular images made in freeway.
In a small test the navigation combined with smooth scrolling back to the top is working now.
