Re: org-tree-slide annoyance

Hi Henry,

Thank you for using org-tree-slide and reporting the issue.
Please use the following patch to avoid the error.

PATCH: 
  Replace the original code with
----
(defun ots-display-tree-with-narrow ()
  "Show a tree with narrowing and also set a header at the head of slide."
  (goto-char (point-at-bol))
  (when (ots-last-heading-position)
    (hide-subtree)			; support CONTENT (subtrees are shown)
    (org-show-entry)
    (show-children)
    (org-cycle-hide-drawers 'all)
    (org-narrow-to-subtree))
  (setq display-tree-slide-string
	(if (equal org-tree-slide-modeline-display 'outside)
	    (ots-count-slide (point))
	  ""))
  (when org-tree-slide-slide-in-effect
    (ots-slide-in org-tree-slide-slide-in-brank-lines))
  (when org-tree-slide-header
    (ots-show-slide-header)))
----

This patch is a tentative code for checking behavior in your environments,
but I think you will be able to open org files without heading.
I'll update it again within a few days.


Best,
Takaaki
