Thanks, but the problem went away (see post #2). I don't know what was going on.

I've actually been using my own font for some time, but I haven't changed it in months. I'm not sure what happened to IE, but 'reverting' it to its factory settings fixed the problem.

I tried that because some comments you've made in the past led me to strongly suspect you're using the embeddable IE control for the right side display.
