+***** The 'horizontal-scroll-bars' parameter was already present and non-nil
+by default in Emacs 24 (although it didn't have any effect).  This
+could cause a problem if you share your desktop files with Emacs 24:
+saving desktop in v24, then restoring it in v25.1 would turn on
+horizontal scroll bars in all buffers.  To resolve this issue, put
+this in your ~/.emacs init file

+  (modify-all-frames-parameters '((horizontal-scroll-bars . nil)))

 **** New functions 'frame-scroll-bar-height' and
 'window-scroll-bar-height' return the height of horizontal scroll
 bars on a specific frame or window.
