Huh! When I click "Cancel", the PDF disappears and then there's just a centered box saying "This file is password-protected. Bennett-Salmon-2010.pdf · 0.94 MB".

Huh! When I click "Cancel", the PDF disappears and then there's just a centered box saying "This file is password-protected. Bennett-Salmon-2010.pdf · 0.94 MB". However, the Download link works just fine and lets me download and read the PDF. Dropbox is weird.
