problem s posterem v LaTeXu2e

[Filip Kadlec]

Dobry den.
Narazil jsem na (pro mne) zapeklity problem pri priprave posteru. Pokud
nektery TeXpert bude schopen mi pomoci, budu mu velmi zauzlovan.
    Kostra zdrojaku vypada asi takhle:

%=== zacatek zdrojaku ===
\documentclass{article}
\usepackage{multicol}
\usepackage{poster}
\mag\magstep5

\paperwidth=210truemm \paperheight=297truemm
\setlength{\fboxsep}{.8truein}%
\setlength{\fboxrule}{.1truein}%
\newlength{\indl}
\setlength{\indl}{\parindent}
\begin{document}

\begin{Poster}[vcenter=true,hcenter=true]
\fbox{
\begin{minipage}{30truecm}
\setlength{\parindent}{\indl}

\begin{center}
  Tady je nadpis
\end{center}

\begin{multicols}{2}
  A tady je vlastni text
\section{Prvni cast}
atd.
\end{multicols}
\end{minipage}}
\end{Poster}
\end{document}
%=== konec zdrojaku ===

( Poster.sty a multicol.sty jsou standartni styly z ftp.muni.cz, podle *.log-u
poster.sty   v1.0  93/05/13  <tvz>
Style option: `multicol' v1.4m <92/09/04> (FMi).
  )

A ted ten problem: pri prekladu dostanu hlasku:
...
(c:/emtex/texinput/latex2e/cslatex/xl2cmr.fd) [1.1
! Undefined control sequence.
\GenericError  ...
                                            #4  \errhelp \@err@      ...
l.40 \end{Poster}

?

Ta hlaska ale zmizi, kdyz misto \section napisu \section*. Dale, kdyz zmenim
\documentstyle na {report}, dostanu tajuplne hlaseni:

...
(c:/emtex/texinput/latex2e/cslatex/xl2cmr.fd) [1.1] [1.2] (poster.aux) )
(\end occurred when \ifnum on line 40 was incomplete)
(\end occurred when \ifdim on line 40 was incomplete)
(\end occurred when \ifnum on line 40 was incomplete)
(\end occurred when \ifdim on line 40 was incomplete)
Output written on poster.dvi (2 pages, 1104 bytes).
Transcript written on poster.log.

Jinak v tomto pripade vysledek vypada celkem tak jak by mel, ale bohuzel az
na cislovani \section ktere je ted 0.1 0.2 atd. jako ve stylu report. A
dale: kdyz necham styl report a misto \section dam \part, dostanu zase to co
v prvnim pripade, tj. ...
! Undefined control sequence.
...

Mam pocit, ze se nejak nesnasi pouzite countery bud s poster.sty nebo
multicol.sty, ale proc??

     Za odpovedi diky predem.
