In case of a slow / poor internet connection (as I'm experiencing here in Rwanda), and if there is a long e-mail message in my Yahoo inbox, Thurnderbird keeps downloading it over and over again. The normal way to fix this is to close Thunderbird, to delete the message in Yahoo web mail, and to open Thunderbird again. Cumbersome, but it works. Until now. I've deleted the message in Webmail, but in Thunderbird it keeps downloading (it is a 7 MB file, and its been downloaded now 8 - 9 times) and doesn't continue with the next unread message. Is there a way to solve this? It takes time and MB, both are precious.....
