No login screen for me either on Opera 12 or the previous 11.5 release. Airdroid 1.0.4 works fine, but 1.0.7 flat out fails. IP login only loads the background image, web.airdroid.com does nothing after scanning QR code or typing in the password. I'd very much would not like to either use IE or roll back to 1.0.4 just to get AirDroid working.
