Again, I thank all of you for providing me with informed, reliable answers.
This time, my question has to do with using trackrevisions and protectedforforms at the same time.
I originally developed my macro in Office 2003. I divided a document into sections, and every third section would have the following property:
activedocument.sections(currentsectionindex).protectedforforms = true
Finally, I would activate revision tracking.
Activedocument.trackrevisions = true
In office 2003, i got the results I wanted. All the sections which weren't protected for forms would allow revisions and the other sections (which had dropdown formfields) would allow formfield interaction by the user.
Then I took this same macro to an earlier version of office, and, oh dear lord, the formfields would just disappear after I changed the value of a dropdown formfield.
Is there any way to keep formfields from disappearing in lesser versions of office?
