Samsung netbook NC10 ; OS Bodhi 3.2.0; Firefox 45.0; Thunderbird 38.6.0. Have 3 eMail accounts on this Notebook. Each of the 3 email accounts exhibit the same message pane anomaly, namely show input headers top pane while simultaneously showing the message pane separated from the header pane by a completely scrollable entire Message source duplication. Don't know how this occurred or when I first noticed early this week. NC10 is a wireless member of my 4 member LAN, 3 of which are wire connected. Each of these 3 desktops use Firefox and Thunderbird. Thunderbird on each have multiple eMail accounts. OS's on the desktops are Win 10, Win 7 Pro and Bodhi 3.1.0. None exhibit the problem outlined for the NC10. Appreciate any suggestions/solutions. I can follow explicit, detailed terminals instructions, if required. Otherwise I'm an experienced Ubuntu User and a dabbler in exploring Live discs of various distros. Thank you. wenco
