// Known bugs :
			// If ie4.5 mac, please press apple-t to remove sidebar, otherwise everything is pushed 20px to the right...
			
			// Corrected bugs :
			// 25.01.2001 - When the height of the span "content" was less than the height of the span "contentClip" a javascript error occured, function changed : move()
			// 21.02.2001 - Scrolling text wasn't selectable in ie, function changed : move()
			// 05.03.2001 - Ie x and y coordinates was wrong when page was scrolled, function changed : getMouse()
			
			// 19.04.2001 - Finally able to remove browser-scrollbar if content is longer than the browser is high:
			// Just put this in the style-tag right before the end head-tag:
			// body {margin-left:0; margin-right:0; margin-top:0; margin-bottom:0; width:100%;height:100%;overflow:hidden}
			
			// THIS IS ALL THE PARAMETERS FOR THE SCROLL BAR :-)
			var upH = 12; // Height of up-arrow
			var upW = 11; // Width of up-arrow
			var downH = 12; // Height of down-arrow
			var downW = 11; // Width of down-arrow
			var dragH = 21; // Height of scrollbar
			var dragW = 10; // Width of scrollbar
			var scrollH = 180; // Height of scrollbar
			var speed = 1; // Scroll speed
			
			// And now... go to the bottom of the page...
