The mdframed package offers the options style=1 and style=3 to have the frames drawn by tikz or pstricks respectively. Using either of these options means that the frames around my boxes just aren't drawn at all.
The following produces the first box with a frame, and then two paragraphs without frames.
\documentclass{article}
\usepackage{lipsum}
\usepackage{mdframed}
\begin{document}
\begin{mdframed}
\lipsum[1]
\end{mdframed}
\begin{mdframed}[style=1]
\lipsum[1]
\end{mdframed}
\begin{mdframed}[style=3]
\lipsum[1]
\end{mdframed}
\end{document}

Any answers?
mdframed.sty 2010/05/14 v4a: mdframed, but not with the latest version. Note that this version doesn't even load TikZ (the older one does). – Andrey Vihrov Jun 16 '11 at 12:07\listfiles. This must be a bug... – Seamus Jun 16 '11 at 12:11
