I ran a TB 3.0 beta 3 on a computer to access gmail via imap - all good
Then I changed the password in gmail from the web page.
TB didn't ask me to enter a new password, instead kept trying the old password stored in TB until google locked the account - I then had to run the unlockcatchpa app to reset the gmail account.
At that point, TB did ask for the password.
I will find a computer shortly to test this further.
