Latest Calibre (2.35) will not let me add books using drag and drop anymore.
I've got Calibre 2.35 on both Win 8.1 and Win 10, but neither works - an older Calibre version on Win 7 works fine. (Most of my books are added via drag and drop from Kindle content.)
I've tried going back to an older version, but that doesn't work either - I get a dialog about modifying or repairing when i try to overwrite the latest version.
Any suggestions, or any idea when a fix will be coming??
