Hi Eric

I've just done this - emacs -Q, the minimal .emacs from your previous email, and your  piece of org/beamer.

It  creates blocks, examples and columns - so it works as it should. Next - but not immediately - is to find out why my usual .emacs doesn't work.

Thanks for all of your help in sorting this out. I look forward to using org-mode to create slides.

I'll report if I find the problem.

Bill
