MimeWriter and PDFs

[Brandon]

Hoping I can get a little help here...

I've got a global nested list of recipients, each containing a file
name and an e-mail address. The process that generates the PDFs has no
problem - I'm saving them to the hard drive, and opening them seems to
not be a problem.

However, once I attach the PDF and send it, I try to open the attached
file and get the following message from Acrobat:

"There was an error opening this document. The file is damaged and
could not be repaired."

I've opened the PDF in a text viewer (the same PDF, before and after
sending it), and it appears that the one that's been sent out has a
bunch of extra data on the end of it.

Anyone? Anyone? Bueller? :)

Thanks,
B.
