Knowledge Explorer behavior

Opened Knowledge Explorer. Can’t figure out how to close it. This wouldn’t be so bad, except when one closes Granthika, and then re-starts, it tries to restore the state of the workplace from the exit, and… Knowledge Explorer is blank, with nothing but a blue spinning circle. (The blue coffee ring of quality) Click on anything in the Connections column, and it behaves as it should, but… that behavior seems odd.

It’s the globe that appears on the right-side on the blue bar on top of the Knowledge Explorer. See screenshot:
