(I am using gVim 7.1 in Windows XP.) If I do a :vsplit, I end up with a scroll bar on the right for the right window and a scroll bar on the left for the left window. When I use my mouse wheel to scroll, the left window scrolls, regardless of which window is selected.
If I do a Edit->Global Settings->Toggle Right Scroll Bar, the right scroll bar disappears. But I am able to mouse-wheel scrolling based on which window is selected. Is there a way to keep both scroll bars, and be able to mouse-wheel scroll based on which window is selected?
