It may do, but AFAICT that has nothing to do with this problem, which
is that X11Forwarding stopped functioning correctly when UseLogin was
enabled.

Not having X11 forwarding and xauth cookie munging is, IMHO, fundamental
missing functionality. (Yeah, I know, I have the source. I could add it. :)


Note: I'm not slagging off against FreSSH. I think it's a product with
high potential, and I'm sure I'll use it when features like X11Forwarding
work ok.  I'm just a little bit curious as to why FreSSH was brought up
here when I don't think it is relevent to the problem at hand :-/
