LinuxQuestions.org - tomboy autostart in xfce, though not on autostart list

Hi,

So I recently upgraded, and switched to xfce at the same time (gnome's just gotten too heavy for my poor computer). When I start xfce, it starts tomboy notes, not once but many times, which is annoying because the window keeps popping up and getting in my way. So ps -ef looks like this:

Tomboy is not set to autostart on the sessions menu, and it is not in /user/share/autostart or in /etc/xdg/autostart. It is not in the autostart menu under gnome.

Advice?

Thanks!
