Nice try Neal, but no, my rheumatism isn't too bad these days. I did manage to figure out what was causing this, and I'll pass it along to the group in case anyone else has the same problem.
In System Preferences, under Universal Access, there is a button for "Trackpad Options…" Clicking that button brings up a window with a "Scrolling" checkbox. That checkbox had somehow gotten turned off, so I put a checkmark in it and now the two-finger scrolling is working again. I had never seen this option before. Another discovery is that it allows you to set it "with inertia" or "without inertia." I wasn't exactly sure what this meant but it became clear when I tried it both ways, which was pretty neat. I left it as "with inertia," which means that when you scroll with your fingers the window will keep scrolling for a bit after you let up, which feels more natural to me. The other setting will stop the scrolling as soon as your fingers stop. There also is a Scrolling Speed slider in that window. Amazing the things you discover by just clicking around in these System Preferences.
