	Description:
	
	Flexible open-window-function. in case of NS/MSIE >=4.0 the popup-window is placed in the center of the screen.
	Embed this script into the head of any html document with <script src="popup.js" language="javascript"></script>. 
	if you want to  use the function, write
	
	<a href="javascript:openPopup2(url,x,y)">Link Title</a>.
	
	Because of size-differences between most browsers, you can change the values for x and y for the most used browsers.
	
	Specified browsers:
	Netscape (3.0 or higher), Explorer (3.0 or higher), OmniWeb (3.0 or higher)
