lines that aren't a border

[drywit01]

I'm futzing with VBA to run some search/replaces, define my heading
styles carefully and the result is that the paragraphs end up with
boxes around them. The non-heading styles I fixed by doing something
(I don't know what). The boxes aren't a border, I turned those off.
They aren't a table, the "convert to text" function is greyed out.
And the worst of it is that control-Q makes it all go away.

What's happening?

I thought it might be a border applied to the text (not the paragraph), but Ctrl+Q would not remove those.
Maybe a frame with a border applied to the frame? Though it would be hard to miss seeing the frame anchor and the hatchet border, if your insertion is in the paragraph.

So I don't really have much of a clue :-/
Have you already put the cursor into one of those paragraphs and used Shift+F1 (Reveal Formatting)?
