I believe the problem should be fixed by now.

Here is the explanation: highlight-changes-mode must be added to
desktop-locals-to-save in order to be saved in the desktop file. To do
this I originally placed

   (add-to-list 'desktop-locals-to-save 'highlight-changes-mode)

inside the function highlight-changes-mode. Therefore things worked when
this function was called, but not when global-highlight-changes was
called. Now I have moved the line out of highlight-changes-mode and
placed it at top level so it is executed at load.
