Yeah , I had the same whish and finalle achieved a similar but more
sophisitaced behavior by the following, without using scroll-in-place:

(defun scroll-down-one-line (arg)
  "Scroll down one line, or number of lines specified by prefix arg."
  (interactive "P")
  (let ((scroll-default-lines 1))
    (scroll-down-in-place arg)))
(defun scroll-up-one-line (arg)
  "Scroll down one line, or number of lines specified by prefix arg."
  (interactive "P")
  (let ((scroll-default-lines 1))
    (scroll-up-in-place arg)))

(global-set-key  [(shift up)] 'scroll-down-one-line)
(global-set-key [(shift down)] 'scroll-up-one-line)


Now emacs scrolls as normal when using the arrow keys, but scrolls
with fixed cursir, around the cursor when I use the arrow
keys+shift. You can bind it to arrow keys only, of course...


Nothing to do with your scroll-lock lamp or function or whatsoever,
whatsoever...


Does this help?
