MS Fax won't queue

I send about 100 faxes, one day a month..I was once able to create the document in Word, 'send to' 'fax recipient', and put as many names from my Office Outlook address book into the send to line as I chose, and Fax would just dial them in order.

I now try to insert say 10 recipients--and the fax doesn't start sending..I check the outbox, and two or three of the recipients are queued (never the first recipient I inserted), and the fax will sit happily for five or ten minutes, then start sending to those in the queue.

If I start over with just one recipient, when I hit finish, the fax starts sending--the faxes waiting in the queue first, as if the new one kicked the others awake.

I uninstalled Norton Internet Security, and that worked...for one fax, then back to the same.

Any suggestions?

>>Edit: A fax to a single recipient works like a champ--two recipients, about half the time----three or more, doesn't work.
