I have the latest version of Thunderbird installed. Regularly I am asked to enter my password before I can receive of send emails. Intitially I was entering the password again but lately I just close Thunderbird and then re-open Thunderbird and this overcomes the question of having to enter my password. However it is not a permanent fix as each day I have to do this action at least 3 times a day. Is there a solution to this problem?
