title: Snoop does not recognize my program
body: <p>I'm building a WPF 4 application.  In the past, Snoop was able to see the application, but now it does not.  This is true with Snoop 2.7.1 and 2.8.0.</p>
  
  <p>That is, I click on the refresh button and my app does not show up in the drop-down control.  I drag the cross hairs over my window and it does nothing.</p>
  
  <p>I really need to snoop my application as I'm debugging some template issues.  Can anybody help?</p>
