title: ShowDialog() behind the parent window
body: <p>I am using <code>ShowDialog()</code> with <code>WindowStyle = WindowStyle.SingleBorderWindow;</code> to open a modal window in my WPF (MVVM) application, but it lets me navigate to parent window using the Windows taskbar (Windows 7).</p>
  
  <p>I've found an answer here: <a href="https://stackoverflow.com/questions/6417558/wpf-and-showdialog">WPF and ShowDialog()</a> but it isn't suitable for me because I don't need an "always on top" tool window.</p>
  
  <p>Thanks in advance</p>
