Not sure if I'm seeing the same bug, or a different one, for me it has started happening a month or two ago, affecting news but not mail.
I normally view sorted by order received, threaded, ascending I quite frequently switch between all and unread messages Using the menu/view/sort-by/order received, I see the "selected" indicator dot against "order received" and I see the "^" sort indicator in the order received column header of the message list pane. If I then swap between unread and all messages using the dropdown in the toolbar, I see the "^" indicator moves to the date column header, at this point the menu/view/sort-by still shows the selected indicator dot next to the order received entry But if I then navigate to a different group, and then switch back to the original group, there is no longer *any* indicator in the menu under view/sort-by and the sorting is messed up. I can always reselect order received and it will sort properly until I alter the all/unread toggle and navigate between different groups, then the sort is broken again.
