During playback, cursor is no longer automatically visible

During playback, the default was for the cursor to stay always onscreen, with the pages moving forward automatically. But now the pages stay fixed, and so the cursor moves off-screen. How do I reestablish the default? (Not sure what I did to affect the default in the first place…..)

It’s a setting: Preferences → Play → Playhead. I think it’s “follow playhead” or something.

There’s also a switch at the bottom of the document window.

That’s what I already have checked. So, it should work.

update: I restarted my computer, and that has fixed the problem. FYI
