Okay, I went ahead and found the FireTray (https://addons.mozilla.org/en-US/thunderbird/addon/4868) add on for Thunderbird. The other system trays are for Wintendo only. This does work for me in that it shows the number of unread messages waiting for me along with minimizing Thunderbird to the system tray. <grin> http://www.perfectreign.com/stuff/2008/20081128_thunderbird_notifications.jp...
