// 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}
