My computers are not three years old,one is an 18 month old Sony running windows 7 and the other a Mac with VPC - which allows me to run the Mac on Windows - in this case Windows XP.

I get the same messages + a warning that incens.exe carries a Trojan, and is blocked by McAfee on the Sony, so I cannot even start the tutorial.On the Mac, in tutorial I can enter and store first page, but computer freezes on page two after entering address - apparently a typical Trojan problem?
