Just moved LT from a device running on Win Vista (SP2) to new device on Win 8.1 64 Bit Installed latest TB for this new device and saved both the profiles.ini and profiles data folder onto Dorpbox updated the new TB software on new device - loading profile folder and profile ini file "C:\Users\Martin\AppData\Local\Thunderbird\Profiles" "C:\Users\Martin\AppData\Roaming\Thunderbird\profiles.ini" This has loaded my old settings and I can now send and recieve emails. My issue is: In the navihgation pane everything is like in my last LT but If I select any of the folders - it only shows me the configuration page and not the list of messages in the viewing pane. The only way to to view these message is to right click the required folder and open it in a new tab or window. Then I can view the list of messages! I have read lots online rying to find my specific problem but none relate, please advise? Thanks HG My Screen View to help is atached.
