I'm trying to add a navbar. I watched the video "Navigation Bar Menus", and followed the helpfile.

I selected a navbar from the design gallery & double clicked to edit it. When I go to the Pop-up menu style dialog, no matter what I do to change any parameters, nothing is altered.
For example, the colours. menu background, menu text, or even the font. Whatever I alter, it just doesn't change anything on the navbar.

I saw the button “ungroup to edit graphics” and I tried that, but that looks like I'd have to edit every single button one at a time? That can't be correct, can it?
