Frames Trip Up IE7 Phishing Filter

A feature dating back to the Internet's HTML 3.0 era is causing problems for Internet Explorer 7, forcing Microsoft to issue an update for Windows Vista just one day after its public launch. Web sites using frames causes IE7's phishing filter to evaluate the page multiple times simultaneously, leading to high CPU usage.

Microsoft encourages anyone experiencing this issue, which might not be obvious except to knowledgeable computer users, to download the update. A patch for IE7 on Windows XP and Windows Server 2003 will arrive during February's Patch Tuesday next week, although a direct download is available now from the Knowledge Base article.
