We are a magazine which uses Word's track changes to go through the editing process with writers. Sometimes stories are thousands of words and an early round of editing can have dozens of comments and changes. We recently realized that some comments that
we thought had been deleted have not, in fact, been deleted causing confusion and extra work for the writer and/or editor. We think we've figured out the situation. Here are screen caps to illustrate.
Test file with three test comments. We can see the comments in both the left and right hand sidebars.
Same test file with the words "those drunks could" deleted. You can see from the left hand panel that the comment is still there, but it has disappeared from the right hand side. You can also see the subtle little blue line in the middle of the paragraph
indicating where the comment "sits".
These are my settings.

I have messed around with every track changes setting I could find and nothing helps. Is there some way to make these disappearing comments show up in the right hand sidebar? It is very frustrating to have these comments persisting from
revision to revision confusing the situation.
We do realize one work around to this is to delete the comment before you delete the text, but there are several reasons this is not going to solve our problem, the primary one being that we have no control over how our many, many writers use Word, so even
if we "solve" the problem through our behaviour, a writer could still cause comments to disappear.
Thanks for your help!
