This basically _very_ good new as it tells us that we have to look on  
the client side (I hope).

So we should list up the differences between x2goclient 3.0.1-4  
(Windows and 3.99.0.x (also on Windows).

There are many... Who can do this?

Can you, John, or anyone else give a howto that explains how to  
reproduce this problem on a fresh server install (Debian squeeze) and  
a fresh client install (Windows, what version?, what arch? what  
Xserver? Etc.). We have to try to address this issue in a very generic  
way if we/you want it solved.

Expecting a debugging recipe to trace this bug... THANKS!

Greets,
Mike
