Jens,

That is not really a satisfactory way to deal with this bug for the near 
term. In passing I note that another system under Linux does not have this 
problem. My real point is that although X11 has this deficiency, in the 
end it is Mathematica that behaves poorly, i.e. it is a bug in 
Mathematica or at least a mistake that the developers made in their 
choice of X11 or whatever. I did not pay money to be told that Mathematica is 
fine, it is X11's fault. Rather, I bought Mathematica to do a job and it doesn't.
