Tomcat, you are still including KB917159 in your XP list, which was replaced with KB923414 in latest updates. Also, in my list I have KB923996v2, which neither of you two include. I'm confused by KB923996v2 because it can be downloaded from this page, but it links to Microsoft Security Bulletin MS06-042 which refers to KB918899, an IE cumulative fix. Let me know what you guys think. Thanks.
