Subject: bug#36107: Global Buttons Stop Functioning When Current Working Directory Changes (Forgot the Subject!)
Date: Thu, 6 Jun 2019 11:58:41 +0000

Thanks for looking at it!

Got an error with that code, though -- here's what I did:

1. Loaded Emacs. Hyperbole auto-loaded.

2. Invoked the "Notes" global button -- just to make sure Hyperbole was
   running and good to go.
   
3. Evaluated provided code

4. Invoked "Notes" global button again and this is what the debugger
   gave me:
