Hi Peter,

thank you for the answer. Actually I was suspecting the xcb library
but I'm not expert enough to be sure about that :-)

I would like to test the patch but I guess is going to take some time
and I can make the computer of my wife instable with all the related
risks :-)
What shoud I recompile exactly ? The whole Xlib, only the xcb library
or it is even more complicated ?

Francesco
