I've been using Calibre for several years, but recently something has changed with the "edit" process. In the past, I would simply view my epub in Calibre, and if I found typos or needed to add punctuation, I simply clicked on the Edit Book icon on the top tool bar, and it opened the page I was on in HTML for editing. Easy peasy.
Now, when I do the same thing as always, I'm getting a different screen with instructions at the top to "Double click a file in the left panel to start editing it."
Only there is no left panel showing --?
