Hi, the tip helped. I just added line "ForwardX11Trusted yes" to the ssh_config file. This fixed also the other problem of Alt Gr not working.
However, the FAQ 5.1 seems to be slightly out of sync with the setup.exe, since file ssh_config resides in /etc after setup, not in /etc/ssh as in FAQ.

Then, could you show the error message from Emacs (if it prints something on the crash) and /tmp/XWin.log from the session? ..............................................................
