stepping through tabular or multicols

[Goebel, Juergen]

Hi,

again I've a little(?) problem with texpower. 

I would like to step through a structure like the following:

\begin{itemize}
\item alsdhalsdhalsd
\item alskdalsdhlashd
\item pros and cons
\multicols{2}                          % multicol.sty
\begin{itemize}{$+$}
\item aaaaa
\item bbbb
\item cccc
\item ddddd
\end{itemize}
\end{multicols}
\item ahdalsdka
\end{itemize}

But I'm always ending with a 'missing item'. Also some experiments
with \parstepwise and \boxedsteps (\bstep) haven't helped me yet.

A test with a two-column-tabular leads to a nearly(!) perfect result.
But after the first entry the tabular steps one millimetre or so upwards.

Any help appreciated
