sshd server exists after first logout

Hi --

I have upgraded my cygwin/sshd installation in the last days, and
encounter the folling problem:

starting sshd allows to establish a ssh session ONCE, and subsequent
attempts to connect via ssh fail. In particular, the sshd service
terminates after the first session exits (it disappears in the Win XP
list of running services). A restart of the sshd service allows the
next connection.

Below is a log of three repeated attemts to establish a ssh session. I
connect to "localhost", but the same pattern prevails if the
connection is done from another machine. At the very end of this email
is a copy of the sshd_config file.

One question, possibley related to this problem, when I run
ssh-host-config,
I don't get prompted
with "CYGWIN=". Is this a problem? (the environment var already exists)

Do you have any idea where the problem might be>
Many thanks for your help!

# This is the sshd server system-wide configuration file. See
# sshd_config(5) for more information.

# This sshd was compiled with PATH=/bin:/usr/sbin:/sbin:/usr/bin

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options change a
# default value.

Port 22
#Protocol 2,1

# Depending on your PAM configuration, this may bypass the setting of
