FM 9 crashes when I try to save .book file with changes on Windows 7 64-bit

[John Sgammato]

I recently got a new Win7 64-bit computer. I installed FM9 new on it and
applied all updates. 
When I open a FM9 book and chapters created on my old 32-bit machine I
can work on it as usual, but when I save the book, FM crashes.
I have reproduced it to the point where simply opening the book file and
Saving As... causes the crash, even when no changes have been made. 
Has anyone else experienced this? Am I missing something simple? Does
anyone have a good insight that will help me track this down?
