The last e-mail I was able to download to my Thunderbird desktop e-mail client was on 7/7/2020 at 1140 EDT. I am using an ACER M3970 with Windows 10 Home. The aforementioned e-mail would normally have been moved by Thunderbird to the "Trash" folder, but I suspect the process was somehow interrupted. Consequently, whenever I open the application, or it is open already and checking for new mail, it simply downloads the same message over and over again. Is the application corrupted? Do I have to reinstall the whole thing or simply create a fresh profile? My husband has his own profile, which is functioning properly. Thanks in advance for any help.
