overflow:auto and Mac browsers

Testing {overflow:auto} on the body tag and/or the html tag. This has been used to hide 'ghost' scrollbars in IE win, when there is not enough content to fill the viewport. This is also used to mimic position:fixed in IE win. Based on the results below, {overflow:auto} on either body and/or html is better hidden from other browsers than IE win, conditional comments can be used for it.
