// file:  		openwindow.js
// functions: 	openwindow(page)
//			ow_size(h,w)
//			ow_height(h)
//			ow_width(w)
//		   	Fdelay(Fwindow)
//			Fwin()
//
// modifications: 1.0 initial openwindow.js
//			1.1 added functions to resize window
//				ow_size(h,w)
//				ow_height(h)
//				ow_width(w)
//			1.2 added the ability to IE and Netscape window forward. This required 
//				two additional functions for IE:
//		   			Fdelay(Fwindow)
//					Fwin()
//			1.3 set a maximum size of the window based on navigator function
//
// purpose:		This is a generic function that allows a user to inline inside html a function
//			to open a window. The window can be opened with the following call:
//				href='javascript:openwindow("/path_to_file/file.html");'
//
//			You must also include the following line before the </HEAD> tag,
//			this will add the openwindow functions to your source:
//				<SCRIPT LANGUAGE="JavaScript" SRC="/scripts/openwindow.js"></SCRIPT>
//
//			Optionally, you can also put in the following inline functions to set
//			the width, height or both for the openwindow size. 
//			To set the height only, use:
//				href='javascript:ow_height(h);openwindow("/path to file/file.html");'
//
//			to set the width only, use:
//				href='javascript:ow_width(h);openwindow("/path to file/file.html");'
//
//			to set the height and width, use:
//				href='javascript:ow_size(w,h);openwindow("/path to file/file.html");'
//
// notes:		You should supply a close button in the file.html, this should be done
//			using the following image: /images/Buttons/close.gif
//			The scrap of code you will need to make this work is as follows:
//
// 			<a href="javascript:window.close();">
//			   <img src="/images/buttons/close.gif" width="92" height="20" border="0" alt="close window">
//                </a>
//
//			This will add the button to the form and create the javascript to close the window.
