Opening a pdf from a blob

Question

Hi Guys,
I know this is a borderline ApEx problem but I have a page whose sole job is to open a pdf from a blob stored in the database.
This code works for most client machines:
DECLARE
l_blob blob;
BEGIN
SELECT letter INTO l_blob
FROM letters
WHERE lett_id = :P44_LETT_ID;
-- owa_util.mime_header('application/pdf',false);
-- tried pdf and octet they work the same?????
owa_util.mime_header('application/octet',false);
htp.p('Content-Length: ' || dbms_lob.getlength(l_blob));
owa_util.http_header_close;      
wpg_docload.download_file(l_blob);
END;
On some machines I get 'Windows cannot open this file ...File: f[7] ...To open this file..........
On most machines this works fine.
I haven't got it to fail with Firefox yet, just IE but only a few machines running IE. Client getting annoyed and I starting to stress.
Many thanks
Gary

Have you already tried adding
htp.p('Content-Disposition:  attachment; filename...as described here?

Maybe it solves the problem, in case IE is a little bit picky. But I really don't know.
