Hmmm...why not send me the log you generated and I'll have a look to see
how big of a difference it is.  Assuming there is just a few changes to
the login packet (Which is already ifdef'ed for 4.2/5.0) and some datatype
changes which hopfully were implemented as new dataypes and not overloaded
with the old numbers, it should be pretty easy.  However, we won't know
under we try.  As far as tools go, the client logs most of the traffic to
a file and I just examine that. There is also a prototype server which a
client can be pointed at which will log client messages.

But, send me your logs anyway and at least we'll know how much of a task
it'll be.  (By the way, have you tried the latest CVS version using 4.2,
I'm very interested in fixing this if it's not working for some reason).
