Indeed, I had to that. I am not really sure that I deleted the correct
ones, though.

I had not tried an xterm in TWM, but I just tried and I see it there,
too. What I found was that the problem went away when I killed hald,
dbus, console-kit-daemon, system-tools-backends and gam_server.

Looks like one of those is triggering it. Now I'll have to try stopping
them one at a time until the problem disappears.
