Version 7 won't accept multiple recipients

We have just upgraded from Ver 6 to Ver 7.
We use MYOB as our account system and it can send emails to multiple recipients through the default client.
So if are to send an invoice (attachment) to and, MYOB would have in it’s address section -;
With version 6 - two emails would be sent, one to each recipient.
Now that we have Ver 7, only the first recipient receives an email. The second receives nothing.
Is there a fix?
