Hi guys, I had some problems producing beamer slides after I installed emacs and org on a new computer. I am using emacs 24.4.1, and installed org (8.2.10 org-2018-08-03) using elpa. I don't seem to be able to get the frame environment even when I set the "H" in the options, e.g. :EXPORT_OPTIONS: H:3 toc:nil *:t ^:nil :t It just gets to subsubsection and then stop. Any idea how to fix this? Thanks a lot! -- Regards, Zhihao Ding
