This question already has an answer here:

I'm writing a presentation in Beamer using the Frankfurt theme. I like the dots that appear in the header denoting various slides (as in this sample), but I can't seem to get them to show up. Compiling various Frankfurt-based presentations found on the Internet is also no help.

My basic slide setup is

\begin{frame}{Here's the title}
    \begin{itemize}
        \item some points...
    \end{itemize}
\end{frame}

How can I get the nice circles in the header of the slides?

Pardon the question, the answer was found in *overflow's "related" section. Long story short: Frankfurt requires subsections in order to render the little circles; updating the subsection counter by \setcounter{subsection}{1} after each new section heading is sufficient for this (if you're not interested in subsections).

    -1 for answering your own question after six minutes; +2 for the "counter" trick. BTW, you should use \stepcounter{subsection} to get the correct color (grey instead of white) for empty circles. – lockstep Jul 15 '11 at 20:31

    @lockstep: self-answering is explicitly encouraged. As is searching for related questions before posting. – Caramdir Jul 15 '11 at 21:12
  • @Caramdir: I'm not against self-answering (I've done it myself frequently), but rather against waiting less than, say, 30 minutes before providing an answer to one's one question. – lockstep Jul 15 '11 at 21:16

    @lockstep: I'd say one should write an answer when one has it. That save the time of everyone else. – Caramdir Jul 15 '11 at 21:20

\documentclass{beamer}
\usetheme{Frankfurt}
\usecolortheme{crane}
\begin{document}
\section{foo}
\begin{frame}{foo}
bar
\end{frame}
\subsection{foobar}
\begin{frame}{baz}
baz
\end{frame}
\subsection{foobarbaz}
\begin{frame}{baz}
baz
\end{frame}
\end{document}

Actually, using \stepcounter{subsection} after every \section{...} gives better results than using \setcounter{subsection}{1}. For my document, the latter misplaced the dots.
