Corrupt Attachments - Notes 6.5, OCN 2003, Outlook 2003

The Outlook Connector for Notes (OCN) is definitely corrupting
attachments.

I received an email with an attached PDF. I read the email (but not
the attachment) in Outlook. I exited Outlook and started Notes. I
opened the mail from Notes, viewed the attachment, and saved a copy.
I exited Notes, started Outlook, and did a Save As on the attachment.
The saved file has size 0. The real PDF has size 154 KB. Properties
in Outlook says that the attachment is 178 bytes.

I'm running Notes 6.5 and the server is Domino 6.5. I'm using Outlook
2003 and the 2003 OCN.

Any suggestions?

Is it possible to tell OCN to replicate FROM Notes TO Outlook but not
back the other way until I can debug this? When I touch the message
in Outlook, it replicates the corrupt attachment back into Notes,
corrupting it there too.

TIA
