Thanks for replying back.  I am therefore reopening this bug.
With your help, we could try to figure out what is going on here.

Does it work like you expect if you evaluate this in emacs -Q?

  (define-key global-map '[S-down-mouse-1] 'mouse-drag-region)
  (define-key global-map '[S-drag-mouse-1] 'mouse-set-region)

If that does not help, could you please try to describe the use-case in
more detail and explain what it is you're trying to achieve?

Thanks in advance.

Best regards,
Stefan Kangas
