Oops, I mistakenly switched my hands in the explanation above!
SO, what I meant to state is that my menu is appearing below my header, justified to the left margin of that column.
I've customized my header with my logo and erased the header text. This leaves a somewhat vacant space above the horizontally oriented menu. Not a good look.
I've switched themes and gone back to AutoFocus hoping for a miracle.
I don't see anything in custom menu or anywhere else that permits rearranging the layout of the basic elements of the theme or an explanation for why the menu would show up there.
Maybe I should delete everything in my library, my posts, my custom header and start over. I won't delete my site, just the content that I've been tinkering with.
