[org-mode] opening org-mode files with emacs

I have been using org-mode for more than a decade now, and have a large collection of notes that grows every day. I have DT index my org directory so that I can find notes amid all the other things I have collected over the years.

In the past, I have been able to right-click on one of these files and open it directly in emacs. For the past few months, this no longer works, and right-clicking on the emacs icon does nothing.
