When starting Thunderbird with only one email account defined and entering the wrong password, the password retry dialog takes a 2+ minutes to appear. This is the message that eventually comes out: "Sending of password for user [userid] did not succeed. Mail server pop.verizon.net responded: [SYS/TEMP] Server error - Please try again later." pop.verizon.net is actually housed on AOL now. This issue never occurred until about a year ago with an upgrade to Thunderbird. When entering the wrong password the dialog appears to be in the background. If you close Thunderbird, the Retry/Enter New Password/Cancel dialog appears immediately. However, TB ends immediately and you have to restart the application.
