To add frame around Verbatim, the framerule must be used to force the frame thickness
to be at least 0.8pt else it will not show in Chrome. (Thanks for Michal Hoftich for finding
why the frame was not showing in Chrome).
So to use a frame and having it show in all three major browsers, use something as follows (until Chrome can handle all rule thickness.
\documentclass[12pt]{article} \usepackage{fancyvrb} \begin{document} \begin{Verbatim}[frame=single,framerule=.8pt] text \end{Verbatim} \end{document}
