Thank you very much, load-prefer-newer did the trick for now.

Please peruse attached to reproduce another glitch that occurs with (setq org-hide-emphasis-markers t). The screencast illustrates what happens in the sample file. The glitch (the pointer automatically dropping to the line below a heading rather than staying at the far right of the heading) seems to occur only when point is on a line below the mouse click location (the mouse is clicked in the empty space to the right of headlines) and it does not seem to happen for headings with children.

Again, thanks a lot.

Here's what I did:

 1. Downloaded org-cycle.el and org-fold-core.el via the link you sent
 2. Verified those are the correct files (found the changes in the files
    that were highlighted in green on the git page)
 3. Copied both files over the ones in my
    c:\Users\PK\Documents\emacs_config\.emacs.d\elpa\org-9.6.1\ folder
 4. Restarted Emacs

Yet, the issue still occurs in the sample file I sent you.

Did I do something wrong?

You did not recompile Org.

You may try to set load-prefer-newer to t to force Emacs loading file
sources if they are modified after the compiled versions.

Or you may open org-fold-core.el manually and run M-x eval-buffer (just
for testing).

Or you may download Org from git
(https://git.savannah.gnu.org/cgit/emacs/org-mode.git/)

Or you may download Org from ELPA devel (http://elpa.gnu.org/devel/).
