Hi,
Jeff listed already a number of questions and suggestions.
Does FrameMaker crash, when you only publish these covers?
Does it make a difference, when you publish via Distiller or via the FrameMaker PDF engine? (You can change this in the Publish pod. Select PDF and edit the Settings file.)
Did you already save these cover files with FrameMaker 17.0.5?
Can you remove some items from these cover files and try again? For example graphics files?
You can also copy everything from a problematic cover file and paste this in a working file.
Best regards, Winfried
Winifred, Jeff:
Thanks for your comments. It seems it was related to a graphic inside a graphic frame inside an anchored frame. When importing it as a graphic frame only, FM does not crash anyore. Strange behavior!
