If I'm changing value in "View" combobox to "unread" and after that back to "All" then all messages are groupped by threads. It's OK. But if I'm leaving news group and go back then all messages in the group are not sorted by threads. Reproducible: Always Steps to Reproduce: 1. Ensure that View | Message | Threaded option is on 2. Open news group and change value in "View" combo box to "Unread" 3. Change value in "View" combobox back to "All" 4. Go to some other new group 5. Go back to the initial news group Actual Results: All messages are not sorted Expected Results: All messages should be sorted by theads
