Thunderbird (20090812)
Windows Vista Home Premium SP2 64 bit

No problems installing. Works as advertised. This much needed add-on fills a gap that standard TB just doesn't have, but honestly should. Thank you, thank you, thank you!

Right clicking the TB tray icon has the expected menu pop up asking to restore program, compose mail, retrieve mail or view addresses ... and of course, close/exit. Options for the add-on are straight forward and make perfect sense.
