I agree, Mark.

And like Mark, I experience corruption with ALL attachment types, not
just JPEG images. .doc files, .ppt files, .zip files, you name it, it
has come through corrupted at one time or another. And also like Mark,
saving a "corrupted" JPEG image to disc will _partially_ display in an
external viewer, like ACDSee.

These attachments are being sent by Windows users, typically using
Outlook, Outlook Express or the mail portion of Netscape.

Mark is definitely not the only to experience it, and unfortunately,
the corruption is not occuring for any of the reasons you mention,
Dierk.

If you read my original messages to the list, you'll see that
forwarding a message that is "corrupt" in TB! to somebody who does not
use TB!, the attachment arrives FINE. If the attachment really was
corrupt, or maligned during network transfer, forwarding the message
to a non-TB! user would also have problems, which they DO NOT. This
indicates that the message was received correctly by TB!, and that it
is stored in TB!'s interal mailboxes fine.

It appears it could be a problem with the BASE64 decoding of MIME
attachments, since the corruption only manifests itself when you try
to "extract" an attachment with TB! (by using the internal viewer or
by choosing "Save" on the attachment).
