GUI button's disappearing behind full screen Texture

hey guy and gals! im working on a main menu screen. pretty simple, i have a full screen texture script and a load level script but heres the rub, when i play the game the GUI button textures appear behind the full screen texture. now if i unclick the check box by the full screen texture script i can see the buttons and if i click it again the buttons appear correctly above the full screen texture. i've tried rebuilding the scene a couple of times and heres the weird part, at first it will all display correctly then it'll go back to being hidden.

i thought maybe it was an order issue kinda like layers over lapping in photoshop but i've moved them into different orders and i get the same issue. both the scripts are applied to a empty Gameobject.

below are the two scripts im using in case its a scripting error.

here is the script for my load level button

 var levelToLoad:String;
 var graphic = TextureGUI(); //(28,23);
 var startPoint = Location();
 var GUIColor:Color = Color.white;
 var noGuiStyle : GUIStyle;
 
 function Start() {
     graphic.setAnchor();
 }
 
 function Update() {
     if (graphic.texture){
         startPoint.updateLocation();
     }
 }
 
 function OnGUI() {
     GUI.color = GUIColor;
     if (GUI.Button(Rect(graphic.offset.x+startPoint.offset.x,graphic.offset.y+startPoint.offset.y,graphic.texture.width,graphic.texture.height),graphic.texture,noGuiStyle)) {
         Application.LoadLevel("test_tunnel");                    
     }            
 }

and here is the display full screen script

 @script ExecuteInEditMode()
 var graphic = TextureGUI(); //(28,23);
 var GUIColor:Color;
 
 function OnGUI() {
     GUI.color = GUIColor;
     if (graphic.texture) {
         GUI.DrawTexture(Rect(graphic.offset.x,graphic.offset.y,
                         Screen.width,Screen.height),
                         graphic.texture,ScaleMode.StretchToFill,true);
     }
 }
 
 function AlphaUp(change:float) {
     GUIColor.a += change;
 }
 
 function setStartColor(color:Color) {
     GUIColor = color;
 }
 
 
 function setDelay(delay:float) {
     if (GUIColor.a > .5) {
         GUIColor.a += delay;
     } else {
         GUIColor.a -= delay;
     }
 }
 
 function AlphaDown(change:float) {
     GUIColor.a -= change;
 }

thanks for any help you guys can give me!
