HA-prosper doesn't obeys the "\part"s

Binary package hint: texlive-latex-recommended

I can't divide a presentation into parts with the package HA-prosper because it doesn't obeys the \part command. Following the HA-prosper's manual, supposedly I can divide my presentation in parts with the command "\part", but only the first "\part" is considered.

Example:
\documentclass[pdf]{prosper}
\usepackage[Fyma]{HA-prosper}

\begin{document}
 \part{Part One}
  \tsectionandpart{First section}
   \begin{slide}{First slide}
     First slide
   \end{slide}
 \part{Part two}
  \tsectionandpart{Second section}
   \begin{slide}{Second slide}
     Second slide
   \end{slide}
\end{document}

This example produces
* Part One
- First Section
    . First Slide
    . Part two
- Second Section
    . Second Slide

I am using the package version 2005.dfsg.3-1 on Feisty
