FWIW, I've been using the new beamer exporter for at least half a year, and I'm convinced the simplest way to handle frames is to set the H: export option to the heading level that you want to turn into frames. That is, typically I use top-level headings for sections, and my slideshows haven't been long enough yet to need subsections, so I set H:2 in one of the #+OPTIONS strings at the top. Then all "** Second level headings" become frames. No need to specify the beamer_env in the properties drawer. It isn't always the case, but it does seem often to be true that simpler input avoids problems. Hope that helps. hjh
