Greetings, In Thunderbird 115.12.2 (64-bit) on Linux Debian 12.6, when I examine "Help -> About", cursor movement in the focused information window moves the list of messages displayed underneath in the unfocused messages window. Hopefully the image suggests the issue. Is this an OS problem or something that can be corrected in Thunderbird? Also, I maintain several accounts, each with several folders. It would be helpful if these all stayed collapsed until selected, with a digit alongside indicating the number of unread messages in each, but recently they each seem to fully expand at inopportune times, making email management rather difficult. Is this the result of a selectable setting somewhere, please?
