Sorry for the dup, Ian. I meant to send to the list the first time.

This sounds a little like something I'm noticing lately. I thought it
was our network at work, but now I see it's really predictable. If
you run "dillo boston.com" on a connection with X forwarded and wait a
few seconds do you see the reset too?
I'm connecting using PuTTY 0.60-2008-09-17 on a windows xp machine
with Xming 6.0.9.31.
