(Forwarding this to address@hidden also)

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
