I want to be able to look at how my document has changed over time. So......I've been learning about markup/tracking changes, etc. but there's a basic understanding I'm missing. If I open a document I've worked on and elect to open the review pane, I see zero insertions. This, after I've made extensive revisions/edits/etc. to the doc. I will even make a bunch of changes at that point, just to make sure: insertions, deletions, add picture, delete it, eliminate paragraphs, etc, etc. The review pane still shows "zero"......what am I not understanding?
