After you install security update 961260 (MS09-002) on a computer that is running Windows Vista or Windows Server 2008, you may experience a problem when you visit some Web pages that are in different Internet Explorer security zones. When the problem occurs, you receive a message that resembles the following:This problem occurs if the navigation causes Protected Mode settings to change from On to Off.
