投影机海报的侧面标题

Question

我喜欢使用 Beamer 在海报图片的侧面写标题。我写了类似下面的内容。但它不起作用。它向我显示一条错误消息：

texify.exe: Windows API error 32: The process cannot access
the file because it is being used by another process.

texify.exe: Data: 1.log

谁能告诉我如何解决这个问题？

\documentclass[final]{beamer}
\usepackage[margincaption]{sidecap}

\begin{document}

\begin{textblock}{}[0,-2.5](33cm,0cm)%
\begin{varblock}[43cm]{}

\begin{SCfigure}
  \centering
\includegraphics[height=10cm]{Figure/Panorama_LB.jpg} 
  \caption{ ... caption text ... }
\end{SCfigure}
\end{varblock}
\end{textblock}

\end{document}
