showModalDialog web form opens again after closing the ModalDialog window

I'm opening a ModalDialog .aspx page (SaveNewDialogWindow.aspx) and setting the returnValue property to store info entered into the controls on that page.   After the ModalDialog window closes, a new window re-opens displaying the same SaveNewDialogWindow.aspx page, but just a new window with none of the features in the original ModalDialog .aspx page.  Can anyone tell me what I'm doing wrong?

Javascript function from the calling page that opens the ModalDialog .aspx page:

    function SaveTemplate()  
    {            
            var returnValue = window.showModalDialog("SaveNewDialogWindow.aspx","","dialogHeight:100px;dialogWidth:280px;status:no");
            return false;        
    }


Javascript function from SaveNewDialogWindow.aspx that sets the returnValue of the window:
function ReturnValue(button)
{
    window.returnValue = "Cancel";
    if (button == "OK")
    {    
        window.returnValue = "OK|" + document.getElementById("chkDefault").checked + "|" + document.getElementById("txtTemplateName").value;                 
      }
      else
      {
          window.returnValue = button;
      }
      window.close()
}

The problem is submutting the form in a modal dialog.
ASP.NET doesn't handle it correctly.

In order to fix this, put this in the head of your html
