In the process of building web sites it is often always important to check your code on multiple platforms and browsers. This rule should extend beyond the obvious Internet Explorer and Netscape Navigator on the Mac and PC. One issue that exists on the PC is that Windows will not, by default, allow you to have/run multiple versions of Internet Explorer. If you try to install an older version of the browser you will get a system error that you have a newer version already installed. A workaround now exists. Joe Maddalone at Insert Title Web Design has published an article entitled Multiple IE's in Windows. In his article Joe describes, in detail, how to accomplish this, before now, impossible task. I followed his instructions and now have IE 5.01, 5.5 and 6 all running perfectly on my Win XP Pro PC. As Joe states in his article you can find previous browser installation files at browsers.evolt.org. Thanks to Justin for the heads up on the article.
