This one is difficult to describe, I'l do my best but I'm sure there will be questions.
The document that was created in Word 2007 but saved as .doc. It was sent offsite and edited in Word 2007 with track changes on 1st reviewer edits shown in red. It was returned to us and now any additional changes tracked, though initially will show a new (blue) color and the reviewers initials, upon save and reopen they all change to red and the initials are replaced with an "A", generic author.
We need to be able to track who is suggesting which changes. This does appear to be document specific as I can get it to work correctly with other documents and new documents. I've tried cutting and pasting the whole document with current set of tracked changes from first reviewer into a new document and it then works with any subsequent edits (color codes, and initials show and save properly)except for the fact that only comments, not formatting edits and deletes, from first reviwer are transferred with a copy and paste so in the end not a good answer. If it weren't a 48 page contract with multiple edits already suggested we could just recreate existing edits by changing the username slightly before creating any new edits.
Other things I've discovered though not sure how they are impacting are:
In Word Options - Advanced - Compatability it shows "Layout this document as if it were created in Microsoft Office 2002" Simply changing this to Word 2007 does not change this behavior, nor does upconverting to .docx.
In trying to specify author using Prepare - Properties - and defining author those changes are not retained on a save either.
