Gee, the time between posts has been so long that it appears the dashboard has changed.  Log in errors show up even after a successful log in.  That makes no sense, but so be it.  Log in successfully, attempt another interaction, be told not successfully logged in.  So I hit the "create a new entry" icon, and we will see what happens. Surely this sort of incident is not happening to just me.

And people wonder why WordPress is so successful?

Simplicity!
