Is anyone else having trouble getting the Table of Contents to show in Calibre's Ebook-Viewer?

I've been using v8.61, and I'm pretty sure the TOC was working before. But today when I clicked on the TOC icon, either nothing happens or the whole screen sort of "shifts/wiggles" but no TOC appears. I figured it was time to update to the latest version, so I installed v8.65, but the same thing happens. No TOC.

Any idea what I'm doing wrong, how I messed this up, or how to fix it? Thanks!

P.S. This happens in both the new paged mode (which is fabulous, by the way) and the old scrolling mode. I also tried it on 3 different books with the same result.
