Try pressing alt once and see if that solves the problem.  I don't recall just what alt does but it is something like to show or hide the interface. It’s a toggle.

I can no longer tab around in Zoom. I have disabled the Zoom add-on thinking
this was an incompatibility issue, but it didn't solve the problem. I'm
using Windows 7.

It is not our differences that divide us. It is our inability to recognize,
accept, and celebrate those differences.
