I think I am using compiz as my window manager (wobbly windows and
stuff). When doing "metacity --replace" xterm does not move anymore
when clicking the titel bar.

This should not be a problem with xterm, because the same happens with
other legacy X11-programs (xclock, xfontconfig). The simplest piece
of software exhibiting the problem is xmessage. The issue must be
with the interaction between one of the libraries xmessage binds and
compiz

Hope this helps.
