Hi Mike,

I gave some more thoughts to your remark, that the position is the wrong 
one.
And you were right. On a system, where users work interactively at an 
attached
screen and use x2go for accessing the system remotely, the fix won't 
work at that
position. There it should be just before the .Xauthority file is 
accessed. I will
see on tuesday, wether I can find that position.

Sincerly

Frank
