I used the recommendation given to me by Art Campbell on framers to set the Tagged PDF feature to "ON" in the Acrobat Settings dialog. That solved the problem; the book distilled to PDF without incident.
Because I have avoided using Tagged PDF (because it bloats the size of the PDF file) in all earlier versions of FM I have used, I contacted Framemaker Tech Support at Adobe today to see if I could have done something else to solve my problem. The tech support specialist told me that the failure to distill a book to PDF is a known issue with FM 8, that it occurs regardless of whether the book is created in Structured or Unstructured FM, and recommended that I continue to use this work-around, or to distill each file in the book individually, until Adobe releases a patch. Thanks to all who took the time to respond to the original message, and thanks especially to Art Campbell, who sent the tagging work-around, which is the most efficient solution for me. -- Valerie Lipow vallipow at gmail.com
