Hi, I am wondering... how do I change Window_Item to only use one column instead of two?

I tried simply changing @column_max to 1 instead of 2 but no luck. ':|

Code: 
#==============================================================================
# ** Window_Item
#------------------------------------------------------------------------------
#  This window displays items in possession on the item and battle screens.
#==============================================================================

class Window_ItemA < Window_Selectable3

  # * Object Initialization

  def initialize
    super(101-27, 31-16, 152, 416)
    @column_max = 2
    refresh
    self.index = 0
    # If in battle, move window to center of screen
    # and make it semi-transparent
    if $game_temp.in_battle
      self.y = 64
      self.height = 256
      self.back_opacity = 160
    end
  end

You also need to change some numbers to draw the items correctly (items != ingame items, but command window items). For example, ...

Code: 
    x = 4 + index % 2 * (288 + 12)
    y = index / 2 * 12

...should be ...

Code: 
    x = 4 + index % 1 * (288 + 12)
    y = index / 1 * 12

And you need to adjust the other values in these lines, too. There also might be other 2's you need to change into 1's, but I can't remember them now...

Edit: Fixed, there was another 2 to change.

Thanks!

Edit 2:

I am getting an error yet again now. I tried with a lot of items to test scrolling. It seems to add an invisible slot on before scrolling down through the items:

Any ideas?
