Just wanted to post a quick note that Microsoft released a patch for Internet Explorer 6 on Windows XP that fixes many memory leaks caused by circular references (details). This is good news, but it only affects those using Windows XP. It’s still best practice to avoid circular references in general, however, this makes the ones you miss a little less troublesome for your users on Windows XP.
