The server probably disconnects because the wrong challenge response is sti=
ll=20
sent. You can see this in Ethereal by looking for a TCP packet with the "FI=
N"=20
flag. If the server sent the first FIN packet, it closed the connection=20
before you did. Note that both server and client send FIN packets to=20
disconnect, but what matters is who sent the first one.

I tried to look at your code, but had a hard time to debug things too (thou=
gh=20
I didn't look days in it). Then I desided to look how Kopete does it - sinc=
e=20
they have MSNP11 support in KDE 3.5 - and found a really nice, well written=
=20
implementation:

http://websvn.kde.org/branches/KDE/3.5/kdenetwork/kopete/protocols/msn/msnc=
hallengehandler.cpp?rev=3D438982&view=3Dmarkup

Actually a really cool example of how Qt/KDE can make C++ easier.

Although I don't like to idea of using other work so easily, I think this=20
saves a lot of time and we'd place the credits in the about dialog.

> btw ive signed up for the mailing list you told me about

Thanks :-) That's why I've sent the reply to the mailing list instead. :-)
