Indeed this seems to be the reason.<BR>
<BR>
I am having the same issue and it only happens with documents that have the following in the message source:<BR>
<BR>
<TT>--------------000205080203070907060608</TT><BR>
<TT>Content-Type: application/vnd.ms-excel; name="mydocument.xls"</TT><BR>
<TT>Content-Transfer-Encoding: base64</TT><BR>
<TT>Content-Disposition: inline; filename="mydocument.xls"</TT><BR>
<BR>
<TT>0M8R4KGxGuEAAAAAAAAAAAAAAAAAAAAAOwADAP7/CQAGAAAAAAAAAAAAAAABAAAAXwAAAAAA</TT><BR>
...<BR>
...<BR>
<BR>
Documents sent with the following source:<BR>
<BR>
<TT>------=_NextPart_000_001C_01CAD63F.66378A00</TT><BR>
<TT>Content-Type: application/vnd.ms-excel; name="mydocument.xls"</TT><BR>
<TT>Content-Transfer-Encoding: base64</TT><BR>
<TT>Content-Disposition: attachment; filename="mydocument.xls"</TT><BR>
<BR>
<TT>0M8R4KGxGuEAAAAAAAAAAAAAAAAAAAAAPgADAP7/CQAGAAAAAAAAAAAAAAABAAAAAQAAAAAAAAAA</TT><BR>

<BR>
Display correctly.<BR>
<BR>
It seems that thunderbird likes to use inline mode instead of attachement. I do not know if it is because the file was dragged and dropped by the user that sent the email though.<BR>
<BR>
Some bugzilla links from upstream that might match this issue:<BR>
