Testing this afternoon, here's a recipe that shows the problem for me (on Emacs 24): 1. emacs -Q [1] 2. M-x eww 3. Enter http://www.fsf.org/campaigns/ at the prompt [2] 4. M-x split-window-below (this is to make the images taller than the window) 5. Scroll down the page with C-n, down to the heading "Secure Boot vs Restricted Boot" (about 51 lines) 6. C-n to the blank line above the image 7. C-n eight times (this scrolls the image at one would expect, one "line" at a time) 8. C-n again [1] Emacs 24.5. Default font is coming up as -xos4-Terminus-normal-normal-normal-*-12-*-*-*-c-60-iso10646-1. [2] Accessed 2015-12-25 18:13 UTC. The `C-n's in Step 7 scroll the image as one would expect. At the second last of those `C-n's, the heading "Secure Boot vs Restricted Boot" scrolls off the top of the window. At the next `C-n' the blank line below the image is at the top of the window. At the next `C-n' (Step 8) which I understand is supposed to move point to the line below the image [Although it would be awesome if it could continue scrolling the image one "line" at a time.], the scrolling "glitches" and point moves _up_ again to the blank line above the image. I will install Emacs 25 now and report back whether I still see the same behaviour on this system. Regards, Neil.
