zipping an FM book

[Deirdre Reagan]

Hi all!

FM 8.0, Windows 3.1

Just kidding -- Windows XP.

My colleague is attempting to WinZip his book.  Every time in the
past, the book has zipped just fine.

This time, when he opens the zipped file, the book doesn't recognize
any chapters.  We've tried zipping it by itself, zipping it on a
different machine, and zipping the folder instead of the files, but
nothing works.

Does this sound familiar to anyone?

Thanks,

Deirdre
