The window can either be a DIV or a separate browserwindow.COMPATABILITY: Works with Netscape 4.x, 6.x, IE 5.x on Windows. Some smallpositioning errors - usually with Window positioning - occur on the Macintosh platform. Due to bugs in Netscape 4.x, populating the popup window with <STYLE> tags may cause errors.USAGE:// Create an object for a WINDOW popupvar win = new PopupWindow(); // Create an object for a DIV window using the DIV named 'mydiv'var win = new PopupWindow('mydiv'); // Set the window to automatically hide itself when the user clicks // anywhere else on the page except the popupwin.autoHide(); // Show the window relative to the anchor name passed inwin.showPopup(anchorname);// Hide the popupwin.hidePopup();// Set the size of the popup window (only applies to WINDOW popupswin.setSize(width,height);// 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()win.populate(string);// set the URL of the window, rather than populating its contents// manuallywin.setUrl("http://www.site.com/");// Refresh the contents of the popupwin.refresh();// Specify how many pixels to the right of the anchor the popup will appearwin.offsetX = 50;// Specify how many pixels below the anchor the popup will appearwin.offsetY = 100;NOTES:1) Requires the functions in AnchorPosition.js2) Your anchor tag MUST contain both NAME and ID attributes which are the    same. For example:   <A NAME="test" ID="test"> </A>3) There must be at least a space between <A> </A> for IE5.5 to see the    anchor tag correctly. Do not do <A></A> with no space.4) When a PopupWindow object is created, a handler for 'onmouseup' is   attached to any event handler you may have already defined. Do NOT define   an event handler for 'onmouseup' after you define a PopupWindow object or   the autoHide() will not work correctly.*/ // Set the position of the popup window based on the anchorfunction PopupWindow_getXYPosition(anchorname) {	var coordinates;	if (this.type == "WINDOW") {		coordinates = getAnchorWindowPosition(anchorname);		}	else {		coordinates = getAnchorPosition(anchorname);		}	this.x = coordinates.x;	this.y = coordinates.y;	}// Set width/height of DIV/popup windowfunction PopupWindow_setSize(width,height) {	this.width = width;	this.height = height;	}// Fill the window with contentsfunction PopupWindow_populate(contents) {	this.contents = contents;	this.populated = false;	}// Set the URL to go tofunction PopupWindow_setUrl(url) {	this.url = url;	}// Set the window popup propertiesfunction PopupWindow_setWindowProperties(props) {	this.windowProperties = props;	}// Refresh the displayed contents of the popupfunction PopupWindow_refresh() {	if (this.divName != null) {		// refresh the DIV object		if (this.use_gebi) {			document.getElementById(this.divName).innerHTML = this.contents;			}		else if (this.use_css) { 			document.all[this.divName].innerHTML = this.contents;			}		else if (this.use_layers) { 			var d = document.layers[this.divName];
