Hi Eric

I've just tried with the totally minimal customization you suggest below - and your  two-column slide which I had already set up
( I haven't had time to go to the website yet and download the one you suggest). Now columns are working  in some fashion
but apparently not blocks.  The two column slide is spread across two slides each with one column.

I'll work on it some more later - and test your slide on the website.

So something else in my emacs customization - which is pretty extensive but (since yesterday) 
has nothing other than vanilla for org-mode (just paths and your org-emphasis-alist ) -
is causing a problem in producing the columns. I'll go through this later too and see if I can find it.

Thanks

Bill

I have no idea what is going on but I can confirm that something is
missing.  If I start emacs with -Q, execute the following

#+begin_src emacs-lisp
(add-to-list 'load-path "~/git/org-mode/lisp")
(require 'org-install)
(require 'org-latex)
#+end_src

visit the small beamer test file I sent to the list earlier today and
export to latex, I get only the title page and the empty outline.
Nothing else.

If I start up with my full initialisation, everything works just fine.

I've gone through my initialisation by eye and cannot see anything that
would make a difference.  I will need to go through this more carefully
as I have many customisations, not only for org...

I don't think so.  Although I do customise mine, if I include this in
the above test (-Q start), it makes no difference.  I do not change the
"beamer" entry in any case.

I will play around later tonight and will get back to you then.
