Reply To: ID Lag Problem

Wow that is strange (both the lag and that your characters turned into ? symbols)

I suggest Rebuilding your Preferences file. (Probably won’t help, but worth trying.)

31 cross-references is not very many. (If you said 310 or 3100 I might worry.)

Do you have all the docs open at the same time? If you open the doc without the book panel open, does it still happen? Does it slow down for any other documents (even new documents)?

Try working with all your panels closed.
