Correct. I have said all along that the message is received and stored
correctly by TB!, so it is not a network or ISP issue. I believe it
is an issue with how TB! "decodes" the attachment when it comes
time to actually EXTRACT the attachment for viewing/use.

Nope. I do not separate out the attachments; I leave them "as is".

In the case of JPEG attachments, clicking the little tab at the bottom
of the window that allows you to view the image results in nothing
but a blank pane when the attachment is "corrupt".

Double-clicking the attachment to view it with TB!'s internal image
viewer results in a JPG Err# 11 or JPG Err# 68.

Saving the attachment (by dragging the icon from the attachment
sidebar, or right-clicking it and choosing "Save") and viewing it in
an external viewer, such as IrfanView, ACDSee, Internet Explorer,
Photoshop, etc. results in a JPEG image that is partially viewable,
and then corrupt at some varying point in the image.

Forwarding the mail to a non-TB! user results in a perfectly valid,
error-free image, as does exporting and re-importing the message (in
most, but not all cases).

I'm just trying to "use" whatever attachment is sent to me! .DOC files
can't be opened in Word (it complains about the file being corrupt),
.PPT files won't open, ZIP files have CRC errors and abort extraction,
etc.

In _all_ cases, forwarding the message (in many of my tests, I would
forward it to my wife's email account; she uses Outlook) results
in a perfectly useable file for the recipient.

Lately, I've been able to avoid the extra steps associated with
forwarding it to her, saving the attachment to one of her shared
folders, copying to my computer via the network, etc. by doing the
Export/Import trick. But on occasion, even that hasn't worked.

I have to believe the problem has to do with how TB! is decoding MIME
attachments. If it was anything else (such as corruption in my mailbox
folders, etc.) I wouldn't be able to forward or export/import the
message and have a useable attachment. So the only explanation is that
100% of the attachment data is there, and decodeable by other mail
programs, but _not_ by TB!.

Several TB! users have verified my claims after I sent them my "Test"
mailbox that contains 2 messages which are corrupt when viewed/saved
by TB! but are fine when forwarded to others.
