Hi Danny, the mixer plugin crashes the panel at logout. The backtraces show (!) : (gdb) bt #0 0x407062d9 in free () from /lib/i686/libc.so.6 Anyway, that prevents the user from quitting (as xinitrc restarts automatically the panel if it crashes) Cheers -- Olivier Fourdan <fourdan at xfce.org> http://www.xfce.org
