# How do i vertically align a tikz picture inside a beamer frame

The beamer frames optinal argument [c] seems to be ignored in the following example:

\begin{frame}[c, fragile, shrink] %seems to be ignored, not aligning vertically
\makebox[\textwidth][c]{ % works, aligning horizontally
\begin{tikzpicture}
\node[draw]{Center Me};
\end{tikzpicture}
}
\end{frame}

How do i need to modify the example to center the node vertically?

Incidentally, a MWE starts (at least) with \documentclass and ends with \end{document}. Sometimes problems are due to package clashes and it's hard to debug them without knowing what packages are being loaded. –  Loop Space Feb 8 '13 at 12:08
