The code below gives nice slides with a navigation bar on top that leads to the different sections (I have no subsections) in the presentation. However, below the navigation bar there is a second bar (grey) without any content that I would like to get rid off because it just takes up space. Does anyone know how to do that? Removing that bar would result in the "perfect" presentation for me.
