Is it possible this is due to the changes in tcpip.sys and/or the tcp
stack? I myself am using a hacked one without these changes, so I could
test things to see if it is, if people can give me a specific set of

Unfortunately, half of the stuff in this thread went clean over my head,
so I could easily be barking up the wrong tree....

third number, be reached, then lobbest thou thy Holy Hand Grenade of
