clipped from: webdesign.about.com Like most Web designers, I need to test my Web designs on as many versions of as many browsers as I can, so that they display correctly for all my customers. Internet Explorer makes that very difficult because IE is built into the Windows OS - and so even if you use a hack, it doesn't display the same as on a stand-alone system.
While it's not easy to install (there are 19 steps) and there are some gotchas (the hard drive image Microsoft provides expires on April 1, 2007), this is still a less expensive way to test your creations on IE 6 while taking advantage of all the changes in IE 7.
