re:'' When I open a message to read it,'' How are you opening email to read: # using a single click to open and read in Message Pane? # using a double click to open in a new tab? # using a double click to open in a new window? When enabled, the 'Message Pane' is not a Preview and by default it displays below the Message List/Thread Pane. For those reading this who do not know - enable/disable location: * 'View' > 'Layout' > 'Message Pane' This is where setting for what a double click opens: * Menu icon > Settings > General * under 'Reading & Display' Open new messages - choose an option What option is currently selected? If opening in a new tab: You can reselect the 'Inbox' tab - but if you have a lot of tabs open then you may need to use the left chevron icon '''<''' located on the left side of the opened tabs. Or use the keyboard 'Ctrl' + 'Tab' keys to navigate through the opened tabs left to right or 'Ctrl'+'Shift'+'Tab' to do the same in reverse - right to left. If opening in a new window : You can use 'Alt'+'Tab' to be able to rotate through any opened windows. Does this method work for you?
