I paid the donation. No! I do not wish to have it back. Mail watcher does not sound so it renders useless to me. I disabled ALL security services in window7. I have sound in Thunderbird as i always had. Ran for some time with no firewall of any sort... Mail watcher is silent.. Testing in add-ons returns positive. No, i have audio anywhere else i tested.
Oh, well.....
