FrameMaker-specific preflight problem: update

[Steve Rickaby]

I tried ensuring that the drop shadow was created by a filer rather than an effect, and imported the illustration as a PDF. The problem remained.

I then tried importing as an .eps: problem fixed.

So it seems to be specific to an interaction between Illustrator drop shadows, FrameMaker's importing of PDF files, and FrameMaker's subsequent PDF generation.

Thanks to everyone who responded to this.
