so recently i got an account for Netflix. in order to watch video, i have to install silverlight. when i start to install it everything thing goes fine until it wants my password. When i put in my password, it doesn't do anything. it would just go back to the install page as if i didn't put in my password. i would repeat again and again and nothing would happen. i have also noticed that this would happen every time i want to install something that requires my password. And yes i have restarted safari and my computer many times and all. Even changed my password and still nothing will happen.
