Bells and Whistles is preventing me from signing messages. I select New message and then click the Outlook box for "Digitally Sign Message". Then when I try to send the message, I get the error entitled Microsoft Office Outlook that says "Invalid Object". If I select OK and then Send again, I get entitled Bells and Wistles says "Failed to save message. Error code 0xF5840108 Invalid Object." I have MS Outlook 2003 with the latest updates. This only happens if Bells and Whistles is installed. I have only turned on "Always reply using: HTML".
