I think Jesus' approach is correct. It only missed the initialization of th=
e
super class:

class Navigator<Watir::IE
 def initialize(maxim)
  super()
  @maxim=3Dmaxim
 end
 def go(url)
  goto(url)
  if @maxim=3D=3D1 then
    maximize()
  end
 end
end

At first I thought calling 'super' would do but then I was pointed out by
him that 'super' calls the superclass' initialize method with the same
number of parameters, so we need parenthesis (good to know :-)

Anyway with 'super()' it seems it works:

naveg=3DNavigator.new(1)
naveg.go("http://www.google.es")

puts naveg.url  # =3D> =3D> "http://www.google.es/"
