There’s a bug in the Windows version of the desktop app where the affordance of the vertical scroll bar for items is smaller than the scroll icon. You can tell when the scroll bar is active when it changes color. It doesn’t change color until you are right-of-center on the scrollbar.
Thank you in advance!
