I'm running El Capitan 10.11.4 and TB 45.4 on a MAC - TB starts normally, mail disappears when clicked on and TB locks at the first folder selected.
Every time I restart TB, this same thing happens: (All my emails are still available) I choose a folder such as Local Folders and the email list appears for that folder. The preview screen shows the contents of the first email I click on (but strangely, the address header is missing, only the text of the email appears). If I double click to open it, this email list disappears and I can't get it back.
ALSO, I can't now click on a different folder to see its contents, the cursor moves but nothing changes in the windows - still an empty list. The app is locked now and I have to shut down TB.
When I restart, its the same.

Fixed it by removing the Lightning extension and restarting. Thanks to those who gave this some consideration.
