When I’m designing websites, I have to constantly check up on the output on many browsers. Internet Explorer 6 seems to be a browser that I often have trouble with. Unfortunately I am using the updated Internet Explorer 7 and downloading older versions from the Microsoft download centre will not let you proceed with a seperate installation of Internet Explorer, you can only have one or the other.
Until now! After searching around I stumbled upon MultipleIEs. Now I can run Internet Explorer 6 for testing purposes as well as having the updated Internet Explorer 7, Firefox, Opera and Safari all on the same Windows installation.
An excellent resource for designers.
