Great with OSX Lion, not so with Mountain Lion
I had Autograph working on Lion, but when I downloaded Mountain Lion a few weeks ago it stopped working! They NEED TO UPDATE this app.
Otherwise, I think all the reports of people not being able to open the application are just people who dont know how to use it. Autograph doesnt open up as a new application window. You just choose "Autograph Now" from the menu bar, and then the Autograph screen pops up. Simply paste the autograph into whatever document you are using. If it starts working for Mountain Lion, then Id give it four stars. It does what it is supposed to and does it quickly.
