ive installed the latest TB on my mac running Yosemite but it wont create any account with known good account details. Ive tried 3 different accounts with a mixture of POP and IMAP but each time the new account (after manual config) hangs saying password OK after clicking done. the bottom of the main window says sending secure login information but it never actually creates the account and the create account window just stays open unless i click cancel (done is greyed out)
