    While you're connected with PuTTY, click on the icon in the top left
    corner to show the system menu and choose 'Event log'. A connection with
    successfull X11 forwarding will show the lines

    2004-10-19 09:39:10 Requesting X11 forwarding
    2004-10-19 09:39:10 X11 forwarding enabled

    If the first line is missing, you haven't configured PuTTY configured
    properly. Otherwise there's still something wrong on the server side.
    Did you restart sshd after setting X11Forwarding to yes?
