# Layout issues with beamerposter

I am having some layout issues with beamerposter. As you can see the vertical alignment does not work properly. Also, the conclusions block is too long.

\documentclass[final]{beamer}
\mode<presentation>
{
\usetheme{Berlin}
}
\usepackage[orientation=landscape,size=custom,width=200,height=120,scale=2.4,debug]{beamerposter}

\begin{document}

\begin{frame}[t]{}

\begin{columns}[totalwidth=\textwidth]

%% 1 column
\begin{column}{0.32\textwidth}
\begin{block}{Problem}
\end{block}
\end{column}

%% 2 column
\begin{column}{0.63\textwidth}

\begin{columns}[totalwidth = \textwidth]
\begin{column}{0.47\textwidth}
\begin{block}{Column 1}
\end{block}
\end{column}
%%
\begin{column}{0.47\textwidth}
\begin{block}{Column 2}
\end{block}
\end{column}
\end{columns}

\begin{block}{Conclusion}
\end{block}

\end{column}

\end{columns}

\end{frame}

\end{document}

For the vertical alignment, you can use the [t] option (or [T] to force it) (see a related question and its second answer, Stable vertical alignment of columns in Beamer)

As for the second point, it is, I think, a problem with the horizontal centering of columns. It may vary from one theme to another (see this answer How to center blocks and columns in beamer). For instance, using the default, the CambridgeUS or the PaloAlto theme, this problem seems to disappear. I guess you would have to try and find another theme that does not cause this issue and suits you.

Here is the code that sorts out the first issue :

\documentclass[final]{beamer}
\mode<presentation>
{
\usetheme{Berlin}
}
\usepackage[orientation=landscape,size=custom,width=200,height=120,scale=2.4,debug]{beamerposter}

\begin{document}

\begin{frame}[t]{}

\begin{columns}[totalwidth=\textwidth,t]

%% 1 column
\begin{column}{0.32\textwidth}
\begin{block}{Problem}
\end{block}
\end{column}

%% 2 column
\begin{column}{0.63\textwidth}

\begin{columns}[totalwidth = \textwidth]
\begin{column}{0.47\linewidth}
\begin{block}{Column 1}
\end{block}
\end{column}
%%
\begin{column}{0.47\linewidth}
\begin{block}{Column 2}
\end{block}
\end{column}
\end{columns}

\begin{block}{Conclusion}
\end{block}
\end{column}

\end{columns}

\end{frame}

\end{document}
