Is anyone having trouble with source code disappearing when returning from the edit buffer?
The #+BEGIN_SRC block is simply empty as far as I can tell, regardless of language. If I add some code to the block in the Org buffer before C-c ' then it also eats the contents. I am running Org-mode version 7.9.2 (release_7.9.2-499-ga29de0) under Emacs 24.2.1. I will be happy to provide more debug/trace information, but I'm not sure how to do that.
