Everything works properly on the MacBook Pro. On the Mac Pro the Evernote Desktop Application is not allowing me to drag and drop files into notes (existing or new notes). I have tried dragging into open note windows, the Evernote icon in the Dock and even tried using the attach icon in the toolbar. I also signed out and signed back in - Uninstalled and reinstalled - and even switched users on the desktop app, but nothing worked. It will not allow me to bring in files (PDFs, PNGs, etc). Both versions of Mac OSX are 10.8 / Both versions of Evernote are 5.1.4 - It works on one computer but does not work on the other.
