This update resolves an issue where the Outlook Web Access (OWA) form would stop responding when you compose a message using the S/MIME control on a client running Internet Explorer 7.0 and accessing a mail server running Exchange Server 2003.
ha. that's funny. i installed the S/MIME stuff in IE7 the other day and after i rebooted i could no longer compose an e-mail in OWA. IE kept crashing on me.
