For my home PCs I typically run the latest and greatest web browsers. I even run Internet Explorer 9 which is even not that bad™. Lately I’ve been vacillating between Firefox and Chrome.
At my wife’s work they’re now using Internet Explorer 8. That’s an improvement, they’ve been on version 6 for years.
This blog’s theme uses CSS border radius effectively and it doesn’t render correctly on version 8. You get square blocks where you wanted round corners. The next version it works fine, version 8 and below not so much.
This is easily done by adding some code to my theme’s functions.php file.
