This problem occurs when I attempt to "Send an Email"
Upon entering text and HTML message in the Message Composition area I click the 'Preview' button. The preview message gets sent and looks fine in the email client. But the original message disappears from the Message Composition window, thus preventing me from sending the message to my list.
I suspect I might have some illegal character in the message. If so I don't know what to look for.
Any help would be appreciated.
