"Hidden Fax Window"

IN the process of trying to resolve some networkign
problems, I repeatedly get a system pop-up tellign me
that a "Hidden Fax Window Needs To Close". This occurs
after my network connection hangs (seperate
problem..related?). When the connection hangs, I have to
reboot my system to get it going again. however, when
shutting down, I get the pop-up mentioned above. Does
anyone know what this is? I do have a fax/modem
installed but am not using it. Thanks.

HELP!!
