title: ASP.NET web app w/parent/child windows-parent times out, doesn't recognize use in child window
body: <p>I've got a Jquery function that I wrote which blacks out the screen after a certain amount of inactivity, creates a pop-up that allows the user to click a button to stay logged in, and logs them out (closing the application window) if they do not respond in time.</p>
  
  <p>We don't technically use master pages, but we do have a parent page in which our header, footer and nav reside, and my Jquery code is called from that window.</p>
  
  <p>My problem is that if one is working in a child window, the parent window doesn't recognize that the system is in use, and will automatically engage at the allocated time.</p>
  
  <p>I know it doesn't exist, but I guess I'm looking for a window.child.settimeout or something like that.  Thanks in advance for your time and any ideas.</p>
