I am having trouble with the very simple task of refreshing a window from another window.  My javascript function is

        function refreshIfExists(winName, winURL)
        {
            var dm = ISGetObject("WebDesktopManager1");
            var wnd = dm.GetWindow(winName);
            if (wnd != null)
            {
                wnd.ContentMode = "UseIFrame";
                wnd.ContentURL = winURL;
                wnd.LoadContent();
            }        
        }
        

The above function is plaed on the page of my WebDesktopManager... and is called by winodws useing parent.refreshIfExists('wndName', 'url');

I can get the WebDesktopWindow and manipulate it with Maximize() and Close() methods, but I am unable to refresh the Window despite trying many different commands.

Please advise.  Thank you!
