That sort of solves the problem. When I have it as IDML file. it seems to work fine but when I resaved it as a normal INDD. the issue came back.
I also just noticed the file sizem and I'm not sure what has happened thre, but its over a Gig and a quarter! thats more than 10 times bigger than the rest of the book combined! I have someone else working on this file with me, so I may have to restor the backup and see whats happening there,
Thank you so much. Your solution did work, but it looks like I might have other problems going on that I didn't see before.
