Why drag and drop stopped working
I am using Calibre under windows 7 (64) and until recently had no problem adding new books by drag and drop onto calibre's main window. After a recent upgrade of Calibre (do not remember which version, but definitely later than 8.5) drag and drop does not work anymore and when I drag books onto calibre a sign appears indicating drop is not possible. I can still import books into calibre using the "add books" button though but this is more cumbersome. I am wondering what can I do to make drag and drop work again. Is this a recent Calibre problem that other users have also experienced or I have to change some of my Windows settings.
