I have a Word document that was probably originally created with Word 2000. We continuously work with this document and have made many changes over the last 15 years. We've made changes to the document using Word 2003, 2007, 2010 and 2013.

Now, when users of Word 2013 use the document, most of the comments do not appear in balloons. A few of the comments do appear in balloons. Users of earlier versions of Word see all of the comments in balloons. All users can see all comments in the reviewing pane.

Show Markup is set for display of all information. I.e., there are checkmarks by "Comments", "Ink", "Insertions and Deletions", "Formatting", "Balloons/Show Revisions in Balloons", and "Specific People/All Reviewers".

We had been saving the document as a Word 97-2003 Document. I converted it to a "Word Document" and the behavior is the same.

Thanks.

Try this in Word 2013: Copy the document content, minus the final paragraph mark, into a new file. Does that make a difference?
