Something in this Script keeps activating UI-Buttons

First of all, hi to you all. I'm trying to use the Standard-Asset-Joystick to controll my character, wich works just fine! But this script (without wich the joystick wont work) keeps activating all my UI-buttons, and i can't deactivate them, while the script is active. Is there a way to get it to run the joystick, and keep it from activating the my buttons?

 using System;
 #if UNITY_EDITOR
 using UnityEditor;
 #endif
 using UnityEngine;
 
 
 namespace UnityStandardAssets.CrossPlatformInput
 {
     [ExecuteInEditMode]
     public class MobileControlRig : MonoBehaviour
     {
         // this script enables or disables the child objects of a control rig
         // depending on whether the USE_MOBILE_INPUT define is declared.
 
         // This define is set or unset by a menu item that is included with
         // the Cross Platform Input package.
 
 #if !UNITY_EDITOR
     void OnEnable()
     {
         CheckEnableControlRig();
     }
     #endif
 
         private void Start()
         {
 #if UNITY_EDITOR
             if (Application.isPlaying) //if in the editor, need to check if we are playing, as start is also called just after exiting play
 #endif
             {
                 UnityEngine.EventSystems.EventSystem system = GameObject.FindObjectOfType<UnityEngine.EventSystems.EventSystem>();
 
                 if (system == null)
                 {//the scene have no event system, spawn one
                     GameObject o = new GameObject("EventSystem");
 
                     o.AddComponent<UnityEngine.EventSystems.EventSystem>();
                     o.AddComponent<UnityEngine.EventSystems.StandaloneInputModule>();
                 }
             }
         }
 
 #if UNITY_EDITOR
 
         private void OnEnable()
         {
             EditorUserBuildSettings.activeBuildTargetChanged += Update;
             EditorApplication.update += Update;
         }
 
 
         private void OnDisable()
         {
             EditorUserBuildSettings.activeBuildTargetChanged -= Update;
             EditorApplication.update -= Update;
         }
 
 
         private void Update()
         {
             CheckEnableControlRig();
         }
 #endif
 
 
         private void CheckEnableControlRig()
         {
 #if MOBILE_INPUT
         EnableControlRig(true);
         #else
             EnableControlRig(false);
 #endif
         }
 
 
         private void EnableControlRig(bool enabled)
         {
             foreach (Transform t in transform)
             {
                 t.gameObject.SetActive(enabled);
             }
         }
     }
 }
