Attached Screenshot of the bottom of the list, scrolled using arrow keys.
This is interesting: arrow keys (arrow keys, numpad keys with/without numlock) don't work for me, not even when the first row is selected.
Mouse wheel works as long the mouse cursor is over the list area, and works with the Release Notes as well (that's a mini-browser control), but that also has a vertical scroll bar, so even if the mouse doesn't work, keys do work as well, but not the arrows, the pg up/dn keys, which I guess it's something coming from the vertical scrollbar itself.
