Sometimes, when reading books on my laptop (running OS X 10.8.5 Mountain Lion) I would like to view two separate pages from a book in my Kindle library (or two separate books) at the same time. Unfortunately, the app does not allow more than one window open at once. To get around this, I tried creating a second instance of Kindle.app called Kindle2.app. However, when I try to open it while the first one is open, the icon just bounces in the dock and then disappears. I tried changing the CFBundleIdentifier field in Kindle2.app/Contents/Info.plist, which is an approach I have used to allow 2 copies of nvALT to run at once. However, this does not solve the problem. What should I do?
PS I know I can use Kindle Cloud Reader, but I would like to run a second instance of the app.
