Smooth scroll and hightlight mode

[Michael Chen]

Hi all,

I am using emacs of unicode branch(emacs 23). In order to scroll
smoothly, I setup the following:
(setq scroll-step 1
      scroll-margin 3
      scroll-conservatively 10000)

Meanwhile I enable the highlight current line.
(global-hl-line-mode 1)

But it seems they conflict with each other after my testing. The
screen would jump when scrolling down if both are enabled. So I have
to disable highlight mode even though I think it is wonderful. Anyone
come across this problem? Any hacks?

Thanks a lot,

Ming
