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

Question

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?

Answer 1

The problem is the shrink option. If you remove that then the frame is vertically centred. My guess is that since shrink is meant for cramming stuff that is too big onto the page, the c option gets ignored since if shrink is needed, vertical alignment goes out of the window as the box will fill the entire page.
