Do your check in a mousemove handler and avoid sending messages that may 
pile up. Mousemove also has the advantage of passing the x and y 
coordinates as parameters, so you don't need to read the mouseH. That 
means it responds quicker.

on mouseMove x,y
  if x > 180 or x < 420 then updateThisDisplay
end mouseMove
