I raised this elsewhere but I think it was the wrong place.
I can't order categories, change preferences or add descriptions. Any pop-up menu with tabs only lets me change the contents of the uppermost tab.
I've re-installed twice. It works for a while, usually less than a day, and only intermittently. Then I lose access to the tabs completely.
I this a known bug? Or is there some kind of config I need to do?
