Yes. It's a coincidence. We cron a job every 10 minutes to fetch login 
information from the website.
The error message was expected when you authenticated succesfully but 
not yet authorized.

    I've seen the X weirdly misbehaving when using Mac. We may have to 
file a bug report to Matlab on this one.
    All my other X-Apps,  tunnel under SSH, draws perfectly fine.

    When using Mac, please use the ssh -Y (rather than X). '-Y' enables 
Trusted X11 Forwarding.
   
    Not sure which SSH client you have when using Windows.
    Start Cygwin X Server. If you use Putty, under 'Connection' -> SSH 
-> Tunnels:
          * Check 'Enable X11 Forwarding'
    Which SSH client do you have for Windows ?
   
Thanks,
