I want to use a popup login page and automatically close it when the user
authenticates.  In my OnLoggedIn event handler in the code behind in the
popup page, I have the following:

       protected void OnLoggedIn(object sender, EventArgs e)
       {
           oSessionControl.showProgress("Authentic!!");
           Response.Write ("<script language =
javascript>close();</script>");        
       }

However, the popup window does not close.  Instead, the login document seems
to close and the calling page displays in the same window.  So at that point,
I have 2 browser windows open and visible.  Any clues?
