I am using windows live mail 2012 and have a signature block on all outgoing emails (unless I delete it on specific emails) and I need to edit the content. I have tried the Signature tab under Insert and the only option is "default"which comes up with my current signature block. I edit that, exit the email while saying to save changes, but the next time I try to send an email the old signature block is there. How do I edit the current block?
