Glad the mystery looks like it's solved.

Btw I looped in the orgmode list back here

Dear Org Mode maintainers,

Looping you in on a proposed bug fix for `outline-invisible-p'.

Briefly, the problem is the function returns non-nil for any invisible
text property when it should only do so for the outline property. As a
defsubst, it is difficult to patch for other affected programs.

 I cannot reproduce it in development version. You may want to switch to it.

I'm on the Org ELPA version, which appears to get updated a few times a month. 
How far apart are they?

If the alleged bug has been fixed in the development branch, is it worth then 
finding and merging with stable?

[O] Bug: org-set-tags duplicates tags in org-tag-persistent-alist

[Paul Rankin]

When setting org-tag-alist or org-tag-persistent-alist, calling org-set-tags or 
org-agenda-set-tags will populate select with both alist tags and any tags from 
tagged subheadings.

To reproduce:

$ cat tmp.org
* TODO task:tag1:
$ emacs -Q

(setq org-tag-persistent-alist
  '((tag1 . ?1)
(tag2 . ?2)))

M-x eval-last sexp
M-x find-file RET tmp.org
M-x org-set-tags

Inherited:
Current:tag1

  [1] tag1   [2] tag2   [t] tag1

tag1 is duplicated.

This also occurs if tmp.org is added to agenda and org-agenda-set-tags is 
called, however this bug *compounds* with each additional agenda file 
containing tagged subheadings, e.g. if org-agenda-files contains five org 
files, each with subheadings tagged :work: then org-agenda-set-tags will 
populate with six :work: selections (org-tag-persistent-alist plus each 
additional file).

This bug appears to have been first reported back in 2012 but not investigated:
https://lists.gnu.org/archive/html/emacs-orgmode/2012-12/msg00470.html

GNU Emacs 24.5.1 (x86_64-apple-darwin14.3.0, NS apple-appkit-1347.57) of

Re: [O] Other editors supporting Org-Mode

 I couldn't find anything on the web about it. Therefore, I like to ask
 you if anyone knows a program (another editor) which supports Org mode.

Apologies, I posted this to your email instead of to the group:

You might want to give Trello a look (http://trello.com). It's
web-based, so there is little chance that your technically challenged
friends will break it.

There is a bi-directional sync package for Org Mode called `org-trello'.
It works okay, but obviously lacks many of the features of Org; it's
mostly aimed at task management with teams.
