I'd guess this is something to do with an untrusted xauth cookie with a 20
minute timeout being generated, although exactly how that can happen if you
are using an X server without the SECURITY extension (as Cygwin/X servers have
been built for the past couple of years), I don't quite understand.
See 'ForwardX11Timeout' in 'man ssh_config'
Use 'ssh -Y'
