No actually in one case I just copied ONE book from the Download folder to my pc.. still sat "loading" I also have my books list set up for title not covers so it doesn't have to reload all those thumbnails... I am only guessing that any folder activity , even a simple copy operation must trigger a complete refresh of the contents that would be ok but thenit seems to get stuck at some point... I can download new books from dropbox without any of this happening.. as I said it's no big deal I will just avoid plugging the device in except to update the firmware or when I really need to
