Go to http://www.asp.net and do a search to see a nifty AJAXy popup search results box, powered by Live Search and including some advertising (which I deliberately grayed out below). Look closely, and you’ll see the URLs in the search results (circled in red) have spaces where spaces just shouldn’t be. No surprise, this happens Firefox but not in Internet Explorer.
About the only thing missing is a "Best viewed with Internet Explorer" logo, circa 1998. This really inspires me to click the "Get my own Search Box!" for my site — I’d just love this bug to be reflected in my own work, too.
