Thunderbird V115.13.0 (64-bit) With mail sorted by date = descending & unsorted (my preferred setting so newer messages are at the top of the table list) When there is an email with a file that I detach and save then selected/highlighted message in the inbox moves "up" to a newer message vs staying with the same message With mail sorted by date = descending then when I detach a file the highlighting remain correct on the same selected message Very annoying as I keep having to select/move down the message
