// win.showPopup(anchorname);

// Hide the popup

// Populate the contents of the popup window that will be shown. If you 
// change the contents while it is displayed, you will need to refresh()

// set the URL of the window, rather than populating its contents
// manually
// win.setUrl("http://www.site.com/");

// win.refresh();

// Specify how many pixels to the right of the anchor the popup will appear
// win.offsetX = 50;

// Specify how many pixels below the anchor the popup will appear
