Create a label in Word 2016 and the page is blank... table cells are no longer highlighted like they were in Word 2011.
Selecting Gridlines from the View menu causes the document to display a grid of squares...
Word ➢ Preferences ➢ View ➢ Show ➢ Text boundaries
...displays the border of each label.
However, when finished, one must turn this preference off again or a text boundary will appear in every document.
Dumb.
Office 2011 for the Mac did not exhibit this behaviour.
