Hi, Chris.

Then, you don't use ssh -X/-Y, do you?

Why do you think so? Because they have it in window and didn't specify
any option that exactly means 'turn on X11 forwarding'?
After all, I think that it's not a grave issue as most people use X11
forwarding for rather trusted hosts (or just don't care).

One additional note: it's possible to turn on clipboard forwarding in
RDP and VNC (and it's a very useful thing) but AFAIR in most clients
_one have to specify it implicitly_ (and sometimes there's a separate
option that allows some restricted clipboard access, for example:
copying from remote to local but not vise versa). May be someone will
make a patch to implement such options in X2Go.
