FFIX Skills Activation System, Version 0.3

[Charlie Fleed]

Oh, sorry, I got two posts mixed up...
So, have you tried this:

Code:

class Window_Skill
  #--------------------------------------------------------------------------
  # * Refresh
  #--------------------------------------------------------------------------
  def refresh
    if self.contents != nil
      self.contents.dispose
      self.contents = nil
    end
    @data = []
    for i in 0...@actor.skills.size
      skill = $data_skills[@actor.skills[i]]
      if skill != nil
        @data.push(skill) unless ((SKILL_COSTS[@actor.skills[i]] != nil) and (not @actor.active_skills.include?(@actor.skills[i]))) # Edited line
      end
    end
    # If item count is not 0, make a bit map and draw all items
    @item_max = @data.size
    if @item_max > 0
      self.contents = Bitmap.new(width - 32, row_max * 32)
      for i in 0...@item_max
        draw_item(i)
      end
    end
  end
end

put after all the scripts you have?
