A question: After you have closed the program, can you press alt+tab, and hear
how many programs windows thinks you have open?
For example, close Thunderbird, and it doesn't return you to the desktop.

Then, hold down alt, and repeatedly press tab. It will say something like:
program name, row 1, column 1. Program name, row 1, column 2. And so on. How
many columns does it say you have?

If you get any more than one column, then you have something open you may not
know about. Perhaps you aren't hearing the desktop, because it's returning to
an inaccessible window, or a non-speaking Windows notification, or some such.

NVDA would announce desktop and the icon you were on. Now it says nothing
