Glad you posted--I didn't know until now that Mac OS could once again access the QB OSR. Hated having to switch to a PC anytime I needed a quick peek at the OSR.
The same "useless scrollbar" appears using IE on Windows OS, and the list's location has bounced around over the years/versions of IE and/or OSR revisions. A scroll-wheel on your mouse will let you move up and down the list. Scroll gestures might work on Mac OS.
