Version 128.10.2 (Supernova.) Was working fine until three days ago. NO email for the last three days. It does connect to the server, it simply refuses to download anything after the status messages at the bottom have run their course. No error messages. Checked server settings - no changes from last time I saw them. Called email provider and verified settings. They see no problem at their end (of course.) Tried her new computer that has an older version of Tbird installed (115.10.1, (Supernova)) and it works fine. Any known issues with this newer 'Nebula" version, or any ideas of where I should look for the problem? Thanks!
