Divide and Conquer. Yes, a very tried and true method. My next step.
I was hoping that there were some other resources that I was unaware of. I keep thinking that there should be a record, a log of some sort that tracks the process of exporting to PDF, that can be examined.
Sometimes when printing fails with a multipage document, there is a progress window that indicates which page is processing, and when the process breaks down, you can see which page is the offender. I was hoping for something similar, instead of the generic "Export Failed" message.
Thanks -
