Portable Thunderbird doesn't download a Yahoo's account messages
Have just completed the installation and configuration of an account in Port Tbird on a 32 GB thumb drive. Port Tbird does connect to the account in Yahoo and tells me there are 66 messages, but then is unable to download any of then, eventually telling me "There are no messages to download".
The account in Yahoo.com is one of my throw-away accounts and I confirmed that there were unread messages to download. However, Port Tbird attempts valiantly to do so, going around and around in circles, but finally gives up saying "There are no messages to download" which is untrue.
