windows 7 cygwin/XWin session dies

[Arnaud Caubel <arnaud.caubel@lsce.ipsl.fr>]

Hello,

I run my cygwin/XWin.exe session on Windows 7 Professional and this 
session dies when I iconify it during some time (let'say 20 min).
I think the problem is not to iconify it but more to not do anything.
It is very uncomfortable because I have to relaunch it every time I do 
something else (emails, internet,...) more than about 20 minutes...
I do not understand why the X session crashes...
Could anyone help me ?

It seems there is something with : "XDM: Alive response indicates 
session dead, declaring session dead" but I do not know which parameter 
I have to change to modify this behaviour...

Here is the log file of the session :
