Calibre opening books on first click - help?
Just recently upgraded Calibre tonight to 9.39.
Ever since, every time I click just once on a book title, it opens the book. This is really annoying as I prefer to double click to open the book as before.
Is this a new feature or a bug? If a new feature, can I turn it off somehow and go back to where only a double click opens a book?
