Rated 4 out of 5 stars
It works fine, except for one thing. The login isn't remembered. Every time Thunderbird is started (effectively once a day for me) I get two Google login screens (I assume once for calendar, and another for tasks, althouth it's the same account..)
Otherwise, good plugin.
Thanks for the quick response!
Seems to have worked. Let's see for how long, but for now, somehow, re-adding the calendar fixed it. I restarted TB and it doesn't ask for my login again. I'll increase my rating ;)
Can you try unsubscribing from calendar and tasks lists, then re-subscribing and making sure you enter one email address when prompted? I've heard of this issue, but I haven't been able to reproduce it.
