I am using Apple Mail, 2.1.2. I have 2 email addresses, A & B, in the Inbox. If I highlight Email A and click 'new' a new email window comes up but the sender is shown as Email B. If I highlight Email B and click 'new' a new email window comes up and the sender is shown as Email B.
How do I get Email A to show the sender as Email A for the default. Until the last day or so when I used Email A the sender would automatically be Email A but now it defaults to Email B as the sender unless I change it manually.
How do I get the sender for Email A to default to Email A.
Thanks,
