顯示在另一個線程上運行的輔助窗口時任務欄的奇怪行爲

-1

我創建了一個忙框，其中包含一個不確定的進度欄，該進度欄在不同的線程上運行，以便在繁重的任務中主界面無響應時顯示。現在問題是每當我顯示忙碌的窗口時，它就會將開始菜單帶到前面，而應用程序的主窗口全屏運行並在繁忙窗口關閉後恢復正常。顯示在另一個線程上運行的輔助窗口時任務欄的奇怪行爲

Start menu comes to front whenever i show the busy window

Application goes back to full screen once the busy window closes

我可以在我的代碼到處都是這樣做很容易地使用背景工人，但我想要的是一個可重複使用的解決方案。有人能解釋我爲什麼發生這種情況嗎歡迎提出建議。

這裏的BusyBox的

class BusyBox 
    { 
    static BusyBoxWindow BbwP; 
    static Thread WindowThread; 

    public static void ShowBusy() 
    { 
    if (WindowThread == null) 
     { 
      WindowThread = new System.Threading.Thread(() => 
      { 
       SynchronizationContext.SetSynchronizationContext(new DispatcherSynchronizationContext(Dispatcher.CurrentDispatcher)); 
       BbwP = new BusyBoxWindow(); 
       /*BbwP.Owner = HomeWindow.HomeW;*/ // this line throws the exception "The calling thread cannot access this object because a different thread owns it" 
       BbwP.Show(); 

       BbwP.Closed += (s, e) => 
       { 
        Dispatcher.CurrentDispatcher.BeginInvokeShutdown(DispatcherPriority.Background); 
       }; 

       System.Windows.Threading.Dispatcher.Run(); 

      }); 
      WindowThread.SetApartmentState(ApartmentState.STA); 
      WindowThread.Start(); 
     } 
     else 
     { 
      BbwP.Dispatcher.Invoke(new Action(() => { BbwP.Show(); })); 
     } 
    } 

    public static void CloseBusy() 
    { 
     BbwP.Dispatcher.Invoke(new Action(() => { BbwP.Hide(); })); 
    } 
}
