Unavailable font in BOOK file (not in book's files)

[Mark Lehmann]

The "Font is not available" message appears when I open a particular 
book file — repeat, book file only. (Then when I then open the book 
file's files, they all open cleanly.) [FM10, Win7 SP3]
Any ideas about how to fix this (apart from creating a new book file)?

I've tried saving the book file as a MIF, but FrameMaker crashes when I 
click the Save button.

Also:
• Should I be able to save a book file as a MIF (so that I can rummage 
around in it)?
• Is "Remember Missing Font Names" specific to the individual file, or 
to the FM installation? (I need to distribute this book file.)
• I thought only Numbering and Pagination information was saved in a 
book file; now it seems that font information is in there as well. What 
else is saved in a book file?
