One of the things we test extensively on our sites is cross-browser compatibility. We try to make sure that your site looks the same (or as close as we can come) on all major browsers. One would think that all browsers are standards-compliant and would render web pages the same. Not so, especially with Microsoft's Internet Explorer. It's getting better with each release. Speaking of new IE releases, this story says that Microsoft will be rolling out IE9 automatic upgrades to all XP, Vista and Windows 7 users. Hopefully this will mean that the percentage of users who are on IE7 and IE8 will be dropping rapidly soon and we won't have to worry so much about those older versions.
