Framemaker 11 crashes when comparing books

Not answering the original question, but ... 

You can clean up hundreds of lock files in one swell foop. Just use Windows file explorer to search for ".lck" in the relevant folder, sort the results by date, check they're all from the time you opened the book, select them all, and delete.

We've had a lot of practice at this lately!
