Lately I've been having a problem with the BlackBerry calendar. When it notifies me of an appointment I can't change the appointment to a later date or anything. The BlackBerry menu button doesn't work, the back button doesn't work, and the trackball will scroll up and down through the appointment information but when I click on the time so that I can change it it doesn't work. If I try to change the time or date manually by pressing in numbers on the keypad, that works but then I can't save it because none of the other buttons work. Any help would be appreciated. Thanks.
