bug#36107: Global Buttons Stop Functioning When Current Working Director

This is indeed a bug.  Evaluate this function after loading Hyperbole and I believe this will resolve it.  The default-directory was not set properly in this function.

(defun hpath:find (filename &optional display-where)
  "Edits file FILENAME using user customizable settings of display program and location.

FILENAME may start with a special prefix character which is
handled as follows:
  !filename  - execute as a non-windowed program within a shell;
  &filename  - execute as a windowed program;
  -filename  - load as an Emacs Lisp program.

Otherwise, if FILENAME matches a regular _expression_ in the alist returned by
\(hpath:get-external-display-alist), the associated external display program is invoked.
If not, `hpath:internal-display-alist' is consulted for a specialized internal
display function to use.  If no matches are found there,
`hpath:display-where-alist' is consulted using the optional argument,
DISPLAY-WHERE (a symbol) or if that is nil, the value of
`hpath:display-where', and the matching display function is used.

Allows for hash-style link references to HTML, Markdown or Emacs outline
headings of the form, <file>#<anchor-name>.

Returns non-nil iff file is displayed within a buffer (not with an external
