Browser Cross-Platform Compatibility Issues

I came across a post today on LearnKey’s blog titled Why Web Browser Updates are Necessary. For anyone designing Web sites, especially corporate Web sites, I consider this a must-read. As a Web Designer, I have ran into cross-platform compatibility issues more times than I can count. Since I design mainly on a Mac, I also have the issue of difficulty testing sites in Internet Explorer, especially now that Microsoft no longer makes a Mac version of IE. Usually, if a site works in Firefox and Safari, it will work in just about any browser, but IE frequently throws little curve balls into the mix.
