Thunderbird-Tray

My desire is to have TB Tray start automatically with Windows but not to
launch Thunderbird until I do it manually.

Currently, the TB Tray event settings are configured as I want them as
follows:

1) On TB-Tray start - Do nothing.
2) On TB-Tray exit - Do nothing.
3) On Thunderbird exit - Do nothing.
4) On Windows start - Start TB-Tray

However, when TB Tray starts with Windows it always starts up Thunderbird
automatically although the setting is "Do nothing".

(If TB Tray is started manually it does not start Thunderbird with these
settings; it only starts Thunderbird automatically when TB-Tray starts with
Windows.)

Warm regards.
