I am trying to set the vertical mouse scroll wheel so that if I click the wheel once it goes one line in reading the Bible (say ESV). It defaults to 3, so I set it down to 2, then 1, and it seems to scroll the same, about 2 lines. I wonder if Logos uses its own scroll metrics instead of looking at what the user has set in the Mouse applet under Control Panel? In any case I cannot get it to scroll one line at a time, does anyone have luck doing this?
