Not able to access entire cursor field

[Fatale1]

Ok so this is a simple question. I'm trying to play a game called Legend of Zelda Skyward Sword. I have the unofficial build that allows Motion Plus, everything works fine but when I try to create a new game, it asks me for a character name and has "Link" as the default name. Below this is a keyboard layout and an "ok" and "cancel" button. I can't press the "ok" button because it's outside the cursor's range. What do I do to enlarge the range of the cursor? Thank you.

Under Wiimote settings are two numbers for Width and Height. Make those numbers larger.
