Overfull \hbox actually!

The problem is that \vbox has width \textwidth and then the space and rule
thickness of \fbox havw no space left to live in.  The following is now also
a little more kosher than before.

\makeatletter
\newcommand{\infobox}[1]{%
%  \fboxsep3ex  % to change the space between rule and \fbox contents
%  \fboxrule3pt % to change the rule thickness
  \fbox{%
    \addtolength{\textwidth}{-2\fboxsep}%
    \addtolength{\textwidth}{-2\fboxrule}%
    \parbox{\textwidth}{\noindent \strut #1}%
  }%
  \par
  \nobreak
  \vspace*{\baselineskip}
  \@afterheading
}
\makeatother

Cordialmente,  Philip G. Ratcliffe
