Word 2013 document shows non-printing lines around every paragraph when save in the "new" format

[sleake]

I recently installed Word 2013. When a new document opens, the paragraph marker is surrounded by a dotted line box. Every paragraph after that one has a box.

In working with pre-2013 documents, when I attempt to save them, I get a message that some features may be lost saving in the old format, citing in particular Quick Part customizations. Since the document has these customizations, I save it in the "new" format.

See the attached screen shot of a template with customizations, saved in the "new" format. BTW, I sent this document to a colleague, and she doesn't see the boxes that show in the screen shot. I've combed Options and haven't found a setting that seems to relate.

I'd sure appreciate help in getting rid of this distraction. PS: No problems in documents saved with compatibility checked.
