Hi! Some days ago my Thunderbird has hung. It hung very long, because of that I killed Thunderbird’s process. When I start Thunderbird the next time, I was wondered (see please screenshot). Thunderbird made a lot of fantastic errors (see below). List of Thunderbird’s errors: 1. Thunderbird created (by itself) 5 new folders (4 of them are bold on the screenshot). And: 1.1. There are 2 folders ‘Deleted’ (there WAS only 1) 1.2. There is new folder ‘Drafts’ (before that I had this folder, but it had another name) 1.3. There are 3 folders ‘Inbox’ (there WERE only 1) 2. Thunderbird have (randomly) sorted emails between new folders (some emails have putted in one folder, other emails – in another folder; some emails have duplicated – they are in 2 or 3 folders at the same time) 3. Thunderbird have changed way, how to send emails. For example, I have sent an email, but it saved in wrong folder (compared to how it was before) Had anybody such problems with Thunderbird? Is it possible to cure it? I have a feeling, that some configuration file was broken. Grateful for help, Michael
