I've had my iPad for about three months now. A few weeks ago the 'x' next to the autocorrect bubble quit working. No matter where I touch on the screen, including the 'x', the autocorrect suggestion is chosen. I've turned the device off and then on, reset the user dictionary, checked to make sure the screen is calibrated, etc. No luck. I don't mind autocorrect, but I need the option to reject suggestions. Any ideas?
