Loading animation while Application.LoadLevel in UnityFree

Hey there,

is there any possibility in UnityFree to show an loading animation while executing Application.LoadLevel()? In the code below my loadingWheel-object has an animator component. Unfortunately the animation itself is not shown (only the first sprite) - I guess that Application.LoadLevel() is blocking the UI-thread. Could you help me please?

 using UnityEngine;
 using System.Collections;
 
 public class PlayButtonController : MonoBehaviour {
 
     GameObject loadingWheel;
 
     // Use this for initialization
     void Start () {
         loadingWheel = GameObject.Find("LoadingWheel");
         loadingWheel.renderer.enabled = false;
     }
     
     void OnMouseDown() {
         loadingWheel.renderer.enabled = true;
         Application.LoadLevel (1);
     }
 }

Thank you!
