For the record, I'd like to say how I resolved the problem - if I can
be permitted just one more post on the subject ...

I reproduced the bug when I tried installing the current version of
sshd on a second XP machine - DISPLAY=:10.0 every time. (The
sshd_config was exactly as created by ssh-host-config - except for one
change to permit X11 passthru.)

Then I tried reverting to an older version of sshd.exe (dated
September 2005) and hey presto - the bug was magicked away.  So I'm
using that version now.
