It appears your keyboard type is not set properly. Please go to Preferences > General and check the Keyboard Type setting. If you have a device with a full keyboard (a.k.a QWERTY keyboard), you should select the QWERTY keyboard. If you have one of the newer devices that have less number of keys (also called SureType), such as the 71xx, you should select the SureType setting. Which device do you have?

If neither works for you, you can select the third (default) setting. This setting will work on all the devices but not as conveniently. With this setting, you will need to press the RETURN key to go into text input mode to enter something into a field.

Thanks for trying Minuet!
