Could be that since you changed the location maybe the sun is hitting the sensors in the Wiimote or sensor bar. I notice that when the sun enters my room at a certain angle it gets really jumpy. When this happens it'll make the cursor jumpy.
My advice: Close the shades and try again.
"What have i done.? Is it too late to save me from this place? From the depths of the grave? We all are those .. who thought we were brave."
