I have other programs as well such as Skype that asks for permission, but Skype only asked for the permission initially. The strange thing with the Qt client is that it not only asks for once, not even asks every time I start the client but every time I start Windows (7).
Additional info: I use Returnil System Safe to lock down C. Obviously I accepted the permission both for Skype and the Qt client when it was unlocked but the clients just keeps asking and asking for the permission.
Don't think this is a QT issue. I suggest posting your question here:
