IE6 SP2 Update (KB888240)

When you open the Manage Add-ons dialog box on the Tools menu in Microsoft Internet Explorer, some installed add-ons may not be listed. Therefore, for example, you may not be able to select an add-on that you want to disable.This issue occurs because, during the installation of certain add-ons, a flag is set in the registry that prevents the add-on from being managed through the Manage Add-ons dialog box.
