PopupWindow.js
Author: Matt Kruse
Last modified: 3/21/02

DESCRIPTION: This object allows you to easily and quickly popup a window
in a certain place. The window can either be a DIV or a separate browser
window.

COMPATABILITY: Works with Netscape 4.x, 6.x, IE 5.x on Windows. Some small
positioning 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 popup
var 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 popup
win.autoHide(); 

// Show the window relative to the anchor name passed in
win.showPopup(anchorname);

// Hide the popup
win.hidePopup();

// Set the size of the popup window (only applies to WINDOW popups
win.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);

// Refresh the contents of the popup
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
win.offsetY = 100;

NOTES:
1) Requires the functions in AnchorPosition.js

2) 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.
