This is pretty easy:

CHANGE the windowbg entry to the following
.windowbg, #preview_body {
color: #ffffff;
background: url(images/winbg.png) repeat;
background-color: #161616;
_filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(src='/forum/Themes/DigitalGunfire/images/winbg.png', sizingMethod='scale');
_background-image:none;
}
You can use the underscore trick to make IE bend to your will.
THanks, I'll give it a try!
