The release of Microsoft's Windows XP Service Pack 2 has made it necessary to update the Yahoo!7 software with a small patch (125k). Service Pack 2 provides some significant security improvements, but the changes have created conflicts with the following components of the Yahoo!7 software:
Elements of the Yahoo!7 Software rely on Active X Controls. Parts of the software will not display properly without the patch.
The Yahoo!7 Sidebar for Internet Explorer will not load properly without the patch.
Without the patch, Yahoo!7 Messenger will be blocked when it attempts to connect to the Internet.
After the patch is downloaded, all Yahoo!7 software will function properly.
