Incompatibility Help

I wrote an item window script, but when I try to use it, I get an error saying that an RGSS error occurred on Selwyn's Window Cursor. I don't know what is causing the error at all, but I know that the problem is with my script.

Here is the small code I wrote:

class Window_Itemget < Window_Message
  def initialize(itemid)
    @itemid = itemid
    @itemid = ""
    self.x = 2
    self.y_bottom = 5
    self.width = 236
    self.height = 64
    self.contents = Bitmap.new(width - 32, height - 32)
    self.contents.font.name = "Kartika"
    self.contents.font.size = 20
    self.windowskin = RPG::Cache.windowskin("wskin_g3")
    refresh
  end
  def refresh
   def refresh
    self.contents.clear
    self.contents.font.color = normal_color
    self.contents.draw_text(4, 0, 180, 32, itemid)
    end
  end
end

Here is Selwyn's Window Cursor:

class Sprite_Cursor < Sprite

  attr_accessor :true_y
  #--------------------------------------------------------------------------

  def initialize(x = 0, y = 0)
    super()
    self.x = @true_x = x
    self.y = @true_y = y
    self.z = 10000
    self.bitmap = RPG::Cache.picture("cursor") rescue Bitmap.new(32, 32)
  end
  #--------------------------------------------------------------------------
  # ● update
  #--------------------------------------------------------------------------
  def update
    super
    
    if self.y < @true_y
      n = (@true_y - self.y) / 3
      n = 1 if n == 0
      self.y += n
    elsif self.y > @true_y
      n = (self.y - @true_y) / 3
      n = 1 if n == 0
      self.y -= n
    end

    if self.x < @true_x
      n = (@true_x - self.x) / 3
      n = 1 if n == 0
      self.x += n
    elsif self.x > @true_x
      n = (self.x - @true_x) / 3
      n = 1 if n == 0
      self.x -= n
    end
  end
end

[Draycos Goldaryn]

what exactly does the error say? What line does it point to?

 

[Vent]

line 84 on Selwyn's script.
it says : "line 84: RGSSError occurred
disposed window"

I really need to learn aliasing :[

Never mind this thread. Sorry for troubling you. I have decided to scrap that small script and try this in a different way.

I am going to call the message window with script from an event.

Thanks for trying to help.
