Save as .idml, open that and then save as indd again.
Hi @Frans van der Geest (ACP)
To elaborate on your reply...
Is this a confirmation that the file still contains some remnants of the old version, despite it's previous conversion, saving, editing and re-saving?
I presume the .idml procedure is meant to strip the unwanted remnants out for a fresh start.
As a preventative measure, I don't look forward to repeating this procedure for the thousands of .indd files related to the numerous 300-page publications we produce
Any further confirmations of this as a fact would be welcome
Has anyone tried batch automating this procedure?
