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
