Attachment Converted -- how to stop?

[iyd108]

I've used Eudora on Mac for years, now under OS 10.5.8 with Eudora 6.2.4. I almost always find that when I archive an email that I've received with an attachment, by putting it in any of my mailboxes, that when I open it from the mailbox and wish to open that attachment that I find no attachment icon, and that when I scroll to the bottom of the email I find something like the following actual example:

Content-Type: application/octet-stream;
name="AD - Intergral Yoga Catalog 2009 - 2010.pdf"
Content-Description: AD - Intergral Yoga Catalog 2009 - 2010.pdf
Content-Disposition: attachment;
filename="AD - Intergral Yoga Catalog 2009 - 2010.pdf"

Attachment converted: Macintosh HD:AD - Intergral Yoga #5E1B7A.pdf (PDF /«IC») (005E1B7A)[/INDENT]
Then finding the attachment in the Attachment folder is often impossible. Is there a way to make Eudora save the attachment in the original form with the file icon in the email, so that opening it just requires opening the archived email and double-clicking the the attachment icon? It seems like all of my archived emails have the Attachment Converted verbiage once I reopen them.

Thanks for any help!
