I have an issue with using newgroups via NNTP server in Thunderbird. News only load during startup of the program. Whenever the option Get Messages is chosen later, or when it is automatically run by the program, the process seems to get stuck in a loading state. In this state neither can new messages be read (the headers seem to be there and are shown, but the body of the message isn't), nor can new messages be sent (message sending gets stuck in status "Assembling Message")

This has been the case for a few releases already, and is currently present on 115.10.0 (64bit)
