Everytime I open my
docx it shows the changes panel. When I hide it (Revision tab -> Final revision) it solves my problem, but just until I close the app. When I open it again I have to repeat the procedure.
If you want to disable change tracking, accept all changes and de-select change tracking. If you just want to hide the changes panel, there's a setting for how it displays your changes, and you can disable that panel (I apologize for the lack of specifics - I no longer have access to a Word 2007 installation).
