A question regarding the Fax software in XP led me to try it, don't need it as I have a machine, but you do don't you. Got to the end of the Wizard and got a message saying "no modem". Couldn't get it to work (I'd set it to fax my mobile) so shut down. When I re-started, my mobile rang straight away. Then the penny dropped - I was on-line whilst trying the Fax, so the modem was busy. Hope this is of some help to any puzzled souls ou there.
