There shouldnt be that kind of issues although there was some changes to the way the rolodex works in preview mode.
Check to see if you are using custom menus.
I agree with Mr. Vodka,
It sounds like you have a custom menu with the Go To Record item missing. That will disable the book control and scripts/buttons that use go to next record...
If you're sure that's not the case, you might have a file with corruption that 8.5 tolerates and 10 does not--test a recovered copy and see if it works. If it does, try to find a back up that isn't damaged and use it.
that was exactly my problem. Customized menus. I'm thinkin the new way adds more power to what can be accomplished.
I never would have guessed that was the issue
