Unable to set parent for Xceed.Wpf.Toolkit.MessageBox.Show

Question

In my project the Xceed.Wpf.Toolkit is used.

I'm using MVVM i have a MainView.xaml and all other views are UserControls I'm trying to show a message box from the code behind of my UserControl the message dialog parent is not set to it.

I will invoke dialog message when my viewmodel requires.

UserControl.Xaml.cs

   private void DialogMessageRecieved(DialogMessage dialMessage)
    {
        switch (dialMessage.Caption)
        {

            case "Warning":
                Xceed.Wpf.Toolkit.MessageBox.Show(App.Current.MainWindow, dialMessage.Content, "Warning", dialMessage.Button, dialMessage.Icon);

                //i noticed that if i use native message box it works, 
               //by my app fully is implemented by Xceed

                 MessageBox.Show(App.Current.MainWindow,
                dialMessage.Content, "Warning", dialMessage.Button, dialMessage.Icon);
                    break;

        }
    }

When a message box is shown, user switch to another app and come back the application the message box is hidden , it will only be shown after i press ALT + TAB

Fixed issue by downgrading toolkit to Extended.Wpf.Toolkit -Version 2.3.0

There was issue Since v2.4, for the toolkit "the MessageBox owner is not applied".
