Hi Nicolas, Let me clarify to see if I understood things correctly.

If so, does having \begin{frames}..\end{frames} in the exported tex make sense if the documentclass directive says, for example, article? What I'm getting at is, without the LaTeX_CLASS set to beamer, the crucial \documentclass{beamer} directive is missing and the exported LaTeX document won't be compilable[1]. Given the preceding comments are correct, I would then say having a "beamer" class already defined in org-e-beamer will save new users some trouble.

Of course it fails because it explicitly asks for the "beamer" class when that was not defined. Cheers, Footnotes: [1] I tried this with the LaTeX_CLASS set to article, and there were errors in the exported pdf. -- Suvayu Open source is the future. It sets us free.
