In the file list window, if the list is not tall enough for a vertical scroll bar to appear, the scroll wheel will fall back to scrolling the window horizontally. This behavior is unexpected and disrupts reading of the file list.
Meanwhile, when there is a vertical scrollbar visible, there is no way to use the scrollwheel to scroll horizontally.
Possible solution: Make horizontal scroll consistently available with scrollwheel if and only if using Shift key.
