Thunderbird doesn't start anymore. Rated 1 out of 5 stars
Thunderbird 17.0.4 with Lightning 1.9.1 Calendar Function
Last I defined an event which starts and ends in the past.
I'm not sure to enter the dates correctly.
Maybe the first event is in 2000, and this is a weekly event has 3 terms a week.
Since then Thunderbird doesn't start really, but uses the complete processor power.
How can I remove the calendar function completely?
Even after removing and new installation the problem occurs again!
