When you get a key with extra characters stuck all that happens is that the little pop-up with extra characters shows up and doesn't go away. If a key that doesn't have extra characters on it gets stuck it repeats the key-press. One of the keys without extra characters is backspace and I lost a couple of long text messages due to this bug this week. I suggest elevating the importance of this bug.
