TB has been extremely finicky the past few days with send and receive. The biggest issue is that the ''Get Messages / Get All New Messages'' stops responding altogether - it works fine, and then suddenly nothing except (sometimes) the word "null" next to the online icon at the bottom left, and a pulsating blue progress bar in the Activity Manager area, that disappears after a moment. A few times I have been able to "fix" it by going to Server Settings and changing Connection Security to None temporarily, but this doesn't work every time. Another "solution" is to change the password on the mail server, which prompts TB to demand the PW. This is not a good solution, as the password must then be changed on any/every other device that connects to the mail server, and then the problem repeats after some period. Other times, and per a suggestion on another thread with a similar subject line, clicking on the "go offline" icon at the bottom, generates a prompt to download emails before going offline, and this seems to cause a demand for password, which allows emails to be downloaded, but this also seems like a band-aid. What is going on here? Windows 10 64 Bit TB 102.11.0 (64-bit)
