title: WPF Dual Monitor Application Overlay
body: <p>I looked at this thread to create a dual monitor application in WPF: <a href="http://social.msdn.microsoft.com/forums/en-US/wpf/thread/5d181304-8952-4663-8c3c-dc4d986aa8dd" rel="nofollow">http://social.msdn.microsoft.com/forums/en-US/wpf/thread/5d181304-8952-4663-8c3c-dc4d986aa8dd</a> where a WPF Window will be displayed on each of the two monitors.</p>
  
  <p>The issue I am having is that the windows are overlapping - they are both being displayed on the same screen. The Debugger tells me that there are 2 Displays in the System.Windows.Forms.Screen.AllScreens array and that the Top and Left values of the working areas of each screen are 0, -1600 and 0, 0 respectively (which seem to be accurate to me). </p>
  
  <p>Both screens have a resolution of 1600x1200. </p>
  
  <p>Has anyone come across a similar issue before? The monitors are set to 'Extend desktop to this display' in the Screen resolution settings.</p>
  
  <p>Thanks!</p>
