We have had FAXstf 6.0.6 on our Mac for years but rarely used it. It used to work OK, sort of. We tried it the other day and it wouldn't send anything. Wondering what we did wrong. We turned it "ON" in the control strip, dragged the doc onto the application icon, filled in the fax number, quick send, and no one received any of the faxes. We called to verify this. Does anyone know what we are missing here?
