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?
