EditorGUI.ProgressBar not Updating!!! = (

Got it working. It was the for loop causing the issue. I replaced the for loop with a while loop and put a break at the end of the loop. I also had to put in a check to see if the bar should be running. It all works now thanks every one. Here's my new code for any one interested(I will also be posting this in the scripting section of the forums) :

 This class was made by Roger Moore - Digital Egg Studios
 This is a free to use script.
 
 This is for creating custom progress bars in the editor.
 To use just simply create an instance of it in your code.
 
 Example (C#):
 
 using UnityEngine;
 using UnityEditor;
 using System.Collections;
 
 class MyEditor : Editor
 {
     public bool building = false;
 
     void OnGUI
     {
         if(EditorGUILayout.Button("Build"))
         {
             if ( buildingObjects )
                 return;
     
             ProgressBar window = new ProgressBar();
             window.position = new Rect ( Screen.currentResolution.width/2-250, Screen.currentResolution.height/2-73, 500, 146 );
             window.minSize = new Vector2 ( 500, 146 );
             window.maxSize = new Vector2 ( 500, 146 );
             window.ShowPopup ( );        
             window.editorScript = this;
             window.log = "Initialized builder...;
             window.isBuilding = true;
             window.ListLength = 5;
             window.command = new ProgressBar.method(ExampleMethod);
         }
     }
     void ExampleMethod(int index, ProgressBar builder)
     {
         //Do Stuff
     } 
 }
