I did as you advised and then went on to upgrade safari as the system requested it. I now have the old version of yahoo and it's asking me to upgrade safari so that I can get the updated yahoo..help. The system remains slow which I think is to do with Firefox which is trying to be my default search engine. I also have no tool bar showing Microsoft programs or Finder etc etc.,
My system is so bad I will need to take it to Apple thanks for your help.
