Sorry to take so long to get back to you.

We were unable to duplicate this problem here at MIT with fc1 or 4.0 
final, although we do not have a Windows 2000 machine as a Kerberos 
server to test with.  But with a Unix KDC, we were able to telnet 
with forwarded tickets to a variety of different machines in the same 
BetterTelnet session without problems.

It sounds like it could be a problem with the plug-in; try contacting 
the author of the Kerberos 5 plug-in or BetterTelnet.
