Finally, I just discovered the solution too....I deleted the second email in the To line that was separated by a semicolon....it used to work that way in old versions I think. Anyway, I just added the persons email to the CC section and it sent. Nice to know that you can put more than one person in the "To" field separated by a comma and a space.  Problem solved. However, it should not send up a "network connection error".....
