Thanks, Lionel! Seems like this really is a serious communication-bug. Emacs 
and X have obviously sorted it out by now, both patching around a bit. Now it 
is up to TeXmacs to follow suit and fix the problem as well (probably in a 
similar way as Emacs.

For me, the problem is rather fundamental. I did not manage to find any 
setting that allows me to comfortably work in TeXmacs, so I basically have to 
do without until the problem is fixed. I would do it myself, but I don't 
really have the time at the moment :-(

Ciao,
Nobbi
