In messages composed from Mozzila Thunderbird version 1.5.0.5, attachment
filenames that contain greek (ISO-8859-7) characters are not displayed
correctly in IMP 4.1.3, when the length of the filename exceeds a certain
number of characters. Yet when downloaded, filenames appear correct in OS
save dialog window.

Example of a filename encoding that appears incorreclty in IMP:

--------------020001090103010501080506
Content-Type: application/msword;
name*=ISO-8859-7''%C4%EF%EA%E9%EC%E1%F3%F4%E9%EA%FC%E1%F1%F7%E5%E9.doc
Content-Transfer-Encoding: base64
Content-Disposition: inline;
filename*0*=ISO-8859-7''%C4%EF%EA%E9%EC%E1%F3%F4%E9%EA%FC%E1%F1%F7%E5%E9.d;
 filename*1*=oc

Example of a filename encoding that appears correclty in IMP:

--------------080904060007010807050604
Content-Type: application/msword;
name*=ISO-8859-7''%C4%EF%EA%E9%EC%E1%F3%F4%E9%EA%FC%E1%F1%F7%E5.doc
Content-Transfer-Encoding: base64
Content-Disposition: inline;
filename*=ISO-8859-7''%C4%EF%EA%E9%EC%E1%F3%F4%E9%EA%FC%E1%F1%F7%E5.doc

Obviously, when the filename exceeds 19 characters, Thunderbird brakes up
the filename in two parts (filename*0*, filename*1*) which IMP does not
handle or display correctly, but is able to deliver correctly for
download.

Could there be a fix for this to be displayed correctly on IMP?
Thanks.
