I was away from the computer for a few days until Dec 9. I have now found while I can open the program, it doesn't work correctly. At first, it wouldn't delete emails from the inbox. Now, in addition to not deleting the emails from the inbox, it won't download new emails from my ISP server. I checked the server settings and they appear to be correct. I can send a test email to myself and receive it at my ISP email server, but Thunderbird won't download it. I am using what I believe is the current version of the program (Version 140.6.0esr (64 bit). I am not a computer literate person and don't know what I need to do to fix the problem. Help would be appreciated. Thanks
