I used the bouncycastle implementation to add https support, but maybe some things don't work the way they should. Note that without https support, all your login credentials go over the network in clear text which is highly insecure and not recommended. Somebody could intercept your communication and order tickets with your access code. About the QR code: does it help if you run the app in full screen (try Ctrl+Up or the configuration utility) ? Davy
