Hi there,
>> I know this question isnt directly related to the book
Indeed. You're better off posting in a more general forum such as this one:
http://p2p.wrox.com/asp-net-4-539/ or one from this category:
http://p2p.wrox.com/css-445/ as you'll attract more viewers.
That said, you can install as many old browsers on your machine as possible. With IE this is a bit difficult. For that, you could rent virtual machines at
www.vaasnet.com where they have machines with older IE versions. In addition, you could look at services as
http://browsershots.org/
