Thunderbird 3 in System Tray

[paul s]

Hi -

I decided to upgrade tb from two to three and have been searching for a 
solution for a new mail indicator in the system tray...

The new mail icon and the firetray extensions do not seem to work for 
this machine..

kdebase-runtime-4.3.5-2.fc12.x86_64

Also there does not seem to be anything in the preferences for 
persistent indication of new mail.

my question is, what is everybody using to hide it in the task manager, 
restoring from a system tray icon, and to indicate new mail?

cheers
paul
