I have a 200+ page doc, with 20+ sections. I am having problems with adding
cross-reference links in the headers, and instead get "ERROR MAIN DOCUMENT
ONLY".

I also get the same message when I try to add page numbers. It is NOT a mail
merge doc, and I stopped tracking changes with the toolbar icon, but Word
kept tracking them in the headers and footers. When I try to accept (or
reject) all changes, Word crashes every time.

Is my doc somehow corrupt, or can someone explain this to me?

Thanks.
