When I run this codebehind on page load, none of the labels update, and I
don't get any errors.   See if you can figure it out:

public partial class _Default : System.Web.UI.Page
{
   protected void Page_Load(object sender, EventArgs e)
   {
       Thread RETSThread = new Thread(RETSProcess);
       RETSThread.Start();

       Thread RSSThread = new Thread(RSSProcess);
       RSSThread.Start();
   }

   void RETSProcess()
   {
           //Retrieves info from a proprietary Real Estate DB and updates
labels with appropriate information, this also does not work, all of the
labels are left blank
   }

   void RSSProcess()
   {
           //Retreives RSS information and populates a table on the page,
that doesn't come up at all now.
   }

}
