I just got back a huge ass document I’d been working on for a reasearch project. The edits were done by an organisation I work for, and we mostly do the work via email.
The edits are pretty good and will help me a lot. But somehow, they must be using Microsoft Office 97 or some other strange version or something– they edited the document with track changes (which worked fine) but somehow, the copy they sent back stripped ALL the header formatting. The result– the entire document is now unindexed (no more headings and subheadings), and the table of contents is totally fubared.
