While trying to find a work-around for my previous bug (11033), I noticed that disabling Compiz for the time while the Wine fullscreen app runs, fixes the problem. So I can do "metacity --replace" and then run the wine app and it will exit normally. After that I can restart compiz and everything is ok. 

But I can only do this once per session, because after that, I cannot get Metacity to run, because after starting it, Compiz seems to respawn and replace Metacity instantly. Look at this:
 

nx@enigma:~$ ps -ax | grep compiz
Warning: bad ps syntax, perhaps a bogus '-'? See http://procps.sf.net/faq.html
 5818 ?        SL     0:50 compiz glib gconf


nx@enigma:~$ kill  5818
nx@enigma:~$ ps -ax | grep compiz
Warning: bad ps syntax, perhaps a bogus '-'? See http://procps.sf.net/faq.html
 5818 ?        Z      0:50 [compiz] <defunct>


nx@enigma:~$ kill -9 5818 & metacity		=> metacity runs
nx@enigma:~$ compiz --replace glib gconf	=> compiz runs


nx@enigma:~$ ps -ax | grep compiz
Warning: bad ps syntax, perhaps a bogus '-'? See http://procps.sf.net/faq.html
 5818 ?        Z      0:00 [compiz] <defunct>

nx@enigma:~$ kill -9 6310 & metacity		=> metacity DOESN'T run!


nx@enigma:~$ ps -ax | grep compiz
Warning: bad ps syntax, perhaps a bogus '-'? See http://procps.sf.net/faq.html
 5913 ?        Z      0:00 [compiz] <defunct>
 6315 ?        SL     0:00 compiz --replace glib gconf


nx@enigma:~$ metacity --replace			=> metacity still doesn't run


nx@enigma:~$ ps -ax | grep compiz
Warning: bad ps syntax, perhaps a bogus '-'? See http://procps.sf.net/faq.html
 5913 ?        Z      0:00 [compiz] <defunct>
 6319 ?        SL     0:00 compiz --replace glib gconf


It would really help me in regard to my previous bug, if I could run and
replace compiz and metacity as often as I wish. Anyway, the current 
behaviour is very irritating. Also, why do I get the "[compiz] <defunct>" processes?
