I really like Thunderbird, but I don't care too much for new email notifier programs. TB has a setting sto alert the user when a new email arrives, but those settings only give a sound and the visual alert in the notification tray stays on for about 15 seconds. There is no trouble with the sound. I would like to change the visual alert (an envelope) to appear for about 60 minutes. I am not too computer savvy.
Windows 7 64-bit
All programs are up-to-date
Thanks!
