Trouble with cross-references

[pearlrosenberg at nc.rr.com]

Hi Framers,

FrameMaker 7.p576
Windows XP Professional

I have a book with 17 chapters. Every time I open the chapters in it, 
for six of the chapters I get a message that there are unresolved 
cross-references. There are six other chapters with cross-references 
that do not generate this message.

Each time, I search for the unresolved cross-references (every cross-
reference in each of these chapters), double-click on each, replace it 
with the one in the cross-reference dialog box, and save the file. 
Then I save all the files in the book and save and close the book. The 
next time I open the book, the same cross-references are unresolved 
again.

I created this book from an earlier version by copying the files from 
the old directory to a new one. Then I opened FrameMaker, created a 
new book, and added the files to the new book.

Any suggestions on how I can fix this? BTW, when the cross-references 
are unresolved, they correctly identify the heads, chapters, page 
numbers, and so forth.
