OK, after a bite for lunch, I see what the problem is. The CJK environment, in the LaTeX code, must be specified with all capital letters. (I tried changing the simple test file to say "\begin{cjk}" and LaTeX failed, complaining of an unknown environment. The test file does include "\usepackage{CJK}" and it works with "\begin{CJK}" so the lowercase definitely means "misspelled" here.) The Beamer exporter assumes that environment names will be all lowercase: ;; Use specified environment. (t (downcase env))))) I added my entry into org-beamer-environments-extra with the name "CJK" -- so, when org-beamer-- format-block looks up the environment's formatting spec according to the down-cased name "cjk," it finds nothing and then does not render the environment. But, if I were to name the environment-extra as "cjk," then the exporter would write "\begin{cjk}" which I've already found will break. I will temporarily work around the problem by removing "downcase." That should get me going for the slides I need to prepare today and tomorrow. But there must be a more elegant solution. I'm not sure what that is, but I am certain that it is not safe to assume environments will always be named using only lowercase letters. One more reason to fix: There is one out-of-the-box environment, noteNH, which includes capital letters in the name. This one is also broken -- does not appear in the output. I.e., you can encounter the bug without customizing anything. hjh
