Reply To: InDesign CS5 Issues:

Okay, a suggestion from Bob Levine has solved our PDF export problems with CS4 legacy files on CS5:

Rather than exporting to PDF, we added the document to a book, closed the document, and exported the Book to PDF through the Book Options Panel. This circumvented the background export and forced the export to the foreground. The entire 392 page document exported, problem-free.

This fits with Adobe staff's suspicion that the background PDF function is choking and crashing on some legacy files.

Several of the many people on the Adobe thread dealing with this problem have also confirmed that this works (though there's no guarantee it will work for everyone, as there are a few different issues in the PDF engine affecting people differently).

If you have some big legacy files and are having trouble, give it a try.

Thanks Bob!
