I have Thunderbird 24.5.0. When I double click the desktop item to open it up, it opens immediately, but when I'm in the main page with all the folders on the left & the corresponding email details on the right of that same page, it seems to have problems. Before, when I would highlight a certain box / folder (whether it would b “inbox”, “sent” folder, “trash” folder, or whatever, it takes a good 5 min (minimum) to open that certain folder so I can see the emails of that folder. Can u help me determine what is causing this? Just 3 days ago, it was fine. Thank you
