Using the beamer style Berlin

Question

This package makes my beamer presentation go all blue with those dots at the top which tell you which section and subsection I am on, right?

Thing is, when I make my presentation, compile it and then preview it, all the dots at the top aren't in a neat order. For example, in section 1, they go horizontally. The in section 2 they go vertically, and now in section 3, there is some going horizontally and then like 1 dot vertically and then a few more horizontally.

How do I neaten this up?

Answer 1

It's the intended behavior. Horizontal dots show the number of individual frames in that subsection and vertical shows the number of subsections. Each vertical group is a section.

\documentclass{beamer}
\usetheme{Berlin}

\begin{document}
\section{A}
\subsection{AA}
\begin{frame}A\end{frame}

\subsection{AA}
\begin{frame}A\end{frame}

\section{B}
\subsection{BA}
\begin{frame}B\end{frame}
\subsection{BB}
\begin{frame}B\end{frame}
\subsection{BC}
\begin{frame}B\end{frame}
\begin{frame}B\end{frame}
\begin{frame}B\end{frame}


\section{C}
\subsection{CA}
\begin{frame}C\end{frame}
\subsection{CB}
\begin{frame}C\end{frame}
