Yes, this was the answer. I don't use a mouse, just a Thinkpad with a TrackPoint, so scrolling like this isn't something I ever do. I figured out that two fingers on the trackpad scrolls it. Thanks.

Trying to map buttons, and when I click a device I see the first portion of the available buttons to drag to the remote. However, I only see "CC through Digit 1", the first page of the alphabetical list. I see a tiny scroll bar, partially covered by the button list, but it does nothing. Arrow keys do nothing to scroll, cannot resize window as it seems locked in size. Maximizing the app snaps it back to the original size. Windows 10 21H2. C
