win8 store game, crash in window activated event

Code (CSharp):

1.          protected override void OnWindowCreated(WindowCreatedEventArgs args)
2.         {
3.             args.Window.Activated += onActivated;
4.         }

Code (CSharp):

1.         void onActivated(object sender, WindowActivatedEventArgs e)
2.         {
3.             appCallbacks.InvokeOnAppThread(() =>
4.             {
5.                 UnityEngine.Debug.Log("OnApplicationPause " + (e.WindowActivationState == CoreWindowActivationState.Deactivated));
6.             }, false);
7.         }

玩家点击评分按钮后，应用商店就会被打开，调试中有 OnWindowActivated event - Deactivated 和 OnWindowSizeChanged event , m_Initialized=True. ，但是没有OnApplicationPause的输出。这是游戏卡死，无任何响应，过会就闪退了。
If player click review button, market app will be opened. the debug window has "OnWindowActivated event - Deactivated" and "OnWindowSizeChanged event , m_Initialized=True.", but has no "OnApplicationPause". The game maybe death, it does not respond, and will crash after some time.
Excuse me, my English is very bad.

 

If log "hello", no exception. But log e.WindowActivationState and game window is full, the game will death.

 

There have a new bug, if touch xaml ui, unity can handle the touch also.
