problems running ROOT from my laptop using X11

Hi,

I have a problem running ROOT from my laptop. I've setup cygwin and I then use rxvt.exe to connect to one of the machines at the university:

D:\cygwin\bin\rxvt.exe -ls -si -sk -sb -fg black -bg Wheat -fn 7x14 -g 120x24 -T "machinename.domain" -e ssh -X -l mylogin machinename.domain

Now, if I run ROOT on that machine (ROOT 4, with ROOT set up with ROOTSYS=/usr/local/root/v4.02.00/slc3.gcc3.2.3/root)

I have the following error message:

Error in <RootX11ErrorHandler>: BadAtom (invalid Atom parameter) (XID: 39, XREQ: 18) and I cannot open any canvas:

Error in <RootX11ErrorHandler>: BadAccess (attempt to access private resource denied) (XID: 58, XREQ: 102)

Any idea what is the problem ?

If, instead of ROOT, I run other programs opening graphic windows (like PAW or emacs), I don't have such problem.

Any idea what this is related to ?

Thanks for any help/suggestion !

Note: I'm not running ROOT from cygwin (or Windows), I just use cygwin from my Windows laptop to open an xterm !
