How to show my cursor in Pause menu?

Hi. I have a pause menu script, but before that, I disabled my cursor from showing, cause otherwise it looks bad. How can I enable my cursor when i press "Escape" to go to the main menu? The script is this:

 var skin : GUISkin;
 var buttonOutlineAndTextColor = Color.white;
 var creditIcons : Texture[];
 var credits : String[] = ["Team Free Range."];
 var loadMainMenu : String;
  
 private var savedTimeScale : float;
 private var pauseFilter;
 private var currentPage : Page;
 private var toolbarInt : int = 0;
 private var toolbarStrings : String[] = ["Audio", "Graphics"];
 private var firstPersonControllerCamera;
 private var mainCamera;
 enum Page 
 {
     None, Main, Options, Credits
 }
 function LateUpdate() 
 {
     if (Input.GetKeyDown("escape")) 
     
     {
         switch (currentPage) 
         {
             case Page.None : PauseGame(); 
             break;
             
             case Page.Main : UnPauseGame(); 
             break;
             
             default : currentPage = Page.Main;
         }
     }
 }
  
 function OnGUI() 
 {
     if (skin != null) 
     {
         GUI.skin = skin;
     }
         
     if (IsGamePaused()) 
     {
         GUI.color = buttonOutlineAndTextColor;
         
         switch (currentPage) 
         {
             case Page.Main: PauseMenu(); 
             break;
             
             case Page.Options: ShowToolbar(); 
             break;

I saw it somewhere, but can't remember.. And it is great. Everything works, but I want it to show the cursor again, when I go to the Pause menu. Thanks
