X-windows font size...

I am using debian, and windowmaker. I have been able to adjust the
sizes of most of my fonts, but a few things are baffling me. Programs
such as mozilla, and x-chat have menus and dialog boxes with fonts quite
a bit larger then i'd like... I am not sure where I would go to edit
these fonts. I've been all over the config for window maker and I'm not
seeking any options that affect this.. any gurus have any advice?
