Tell me how to fix the problem!

It timed out, or I closed something, or something. Then I tried typing, and Writely figured out I couldn’t prove I was me anymore:
Not logged in - fine. What do I do about that?
Not logged in – fine. But you’re meant to tell me how to fix the problem, or better yet, fix it for me.

Eventually I brought up the login screen in another tab, logged in, and all became good again.
