I need to reboot to get things working again.
You can also hit ALT-F2 to get a command window, and type "r". This
restarts gnome-shell. This always works when I see this and doesn't require
you to close any windows, log out, or reboot.
I'd love to know why this happens, but it's infrequent enough that I just
do the "r" when it does.
