oh, I think I found the answer. I still dunno why does it happen but you can just remove the line with setting dialog window owner. I had the line Owner = Application.Current.MainWindow. As I understood Prism sets the owner by itself. I thought I had a problem with my container but @lekhaPateel uses UnityContainer. So now it works fine
