I just resend this bug report which has been confirmed by Ista Zahn. Updated via git ust now: Org-mode version 8.2 (release_8.2-14-ge5f16b @ /Users/rainerkrug/.emacs.d/org-mode/lisp/) When starting to edit a code block via C-c ' everything works as expected and the code block is highlighted and an indirect buffer is opened. When I click into the highlighted block, I an "send" to the indirect buffer. This behavior changes, after saving with C-s, even when nothing has been edited: the area in the original org file looses its magic, and looks normal again and can also be edited! The indirect buffer stays functional and, upon close via C-c ' saves the changes into the original buffer and *overwrites* changes done in this block in the org document. Rainer -- Rainer M.
