Html – Any reason why I am getting extra spacing underneath.. IE6-7

Is there an image in your div? If there's an image, there's a bug in IE 6 that can cause white space within the div to create extra padding on the bottom

Extra padding shows up with

<div>
<img src="myimage.jpg">
</div>

Extra padding doesn't show up when you change your HTML to

<div><img src="myimage.jpg"></div>

You can also remove extra space inside the Flash movie using the tuneWidth, tuneHeight, offsetTop and offsetLeft arguments to sIFR.replace().
