Hi Jim,
I agree with your comment about varied manifestation between Acrobat versions. I will be passing this thread to my IT rep who is trying to work with Adobe on this one (regarding missing comments - not the name problem). Your suggestion to upgrade and patch might help my problem but the other user with the missing stamp issue has added the patch but it didn't help. It's a mystery.
I appreciate your trying to help even though your own problem is solved.
Thanks!
Dave
