I have upgraded to Thunderbird V3.1.2.
1) Although all my "Sent" subfolders appeared in the same place as in V2, my three "Inbox" subfolders disappeared. I managed to find only two of them by clicking once and once again the right triangle in the "Unified field": a) How can I send them back to the normal place? b) What happened to my third "Inbox" subfolder - Have I lost it forever with all its emails?
2) I cannot create any New Subfolder for "Inbox". I can, but they don't appear anywhere.
3) It keeps asking for my Master Password. I followed instructions to solve it by deleating file key3.db but it didn't work.
