I get a strange behavior on my groupwise clients 8.01 HP... It didn't
happen with the older clients...

If you forward - or ask to reply including attachments - attachments are
not joined !!!

It is not always the case; as far as I analyze the problem, it seems to
happen with received mails where no "to" recipient is filled, but only a
"BC" or a "CC" recipients...

Does somebody has already seen this problem?

It is a very annoying problem ! Everybody here is complaining about
missing attachments...
