I have a 1x1 white PNG pixel that is 50% transparent... I'm using this has a background image.. such as this..

<div style="background: url('1x1.png') repeat; padding: 5px;">

 <div style="width: 100px; height: 100px; background: #000;">Some Text</div>

In IE 7, the pixel actually fades from top left to bottom right... Meaning the top left is the way the pixel should be... but then for whatever reason it fades out at the bottom right..

Anyone ever heard of this before?
