//this code fixes the problem with IE4.5 on the Mac not displaying scroll bars
//the page height is calculated by looping through all of the divs on the page
//and adding the height of the divs then a clear image of the same height is output 
//to force the scrollbars on
	
//i am not sure how many 4.0 versions of IE on the Mac this scrollbar problem
//appears in so i am using this code on any IE version on the Mac including IE5
//since it does not affect the layout in IE5
