Oops, sorry, my reproduction was confusing, I made an error in having both windows contain the same buffer. They should obviously contain different buffers otherwise your response is correct. Try again with: 1. emacs -Q 2. Eval (setq global-hl-line-sticky-flag t) (global-hl-line-mode) 3. C-x 3 (make two windows) 4. C-h n (make one window contain NEWS) 5. C-x o (switch to the other window) 6. Note the line with point is highlighted in both windows 6. scroll-other-window 7. Note the line with point is no longer highlighted in the NEWS window
