Display Issue in IE 6

Hello,

I'm having issues with a new layout in IE 6.

The HTML is as follows:

    <div id="gsContainer">
        <div id="gsLeftBorder"></div>
		<div id="gsRightBorder"></div>
		<div id="gsContent">
			<div id="gsHeader">Heading</div>
			<div id="gsBox">
				Some content
			</div>
		</div>
	</div>

Code (markup):

The CSS is as follows:

#gsContainer {
	position: relative;
	width: 795px;
	height: 185px;
	margin: 0 0 15px 0;
	padding: 0px;
}

	#gsLeftBorder {
		float: left;
		position: relative;
		margin: 0px;
		padding: 0px;
		width: 4px;
		background-image: url(/images/Left.gif);
		background-repeat: no-repeat;
		height:185px;
	}

	#gsRightBorder {
		position: relative;
		float: right;
		margin: 0px;
		padding: 0px;
		width: 4px;
		background-image: url(/images/GreenRight.gif);
		background-repeat: no-repeat;
		height:185px;
	}

	#gsContent {
		position: relative;
		height: 185px;
		margin-left: 4px;
		margin-right: 4px;
		width:779px;
		padding: 0px;
	}

	#gsHeader {
		position: relative;
		height: 25px;
		margin: 0px;
		padding: 6px 0 0 10px;
		width:769x;
		color: #fff;
		font-size: 14px;
		font-family: arial;
		font-weight: bold;
		background-image: url(/images/Header.gif);
		background-repeat: repeat-x;
	}

	#gsBox {
		position: relative;
		height: 129px;
		margin: 0px;
		padding: 25px 5px 0px 31px;
		width:743px;
		color: #000;
		font-size: 11px;
		font-family: verdana;
		background-image: url(/images/Back.gif);
		background-repeat: repeat-x;
	}

Code (markup):

The display looks fine when I test in IE 7, FF2, and Safari, with the content appearing with a clean "header" on top, and some inner content with borders on the left & right side.

However, when viewing in IE6, the inner content (div "gsContent") is somehow too wide, and is pushed to the live after the "gsContainer" div.

When I play with the widths, if I shave 8px of width off gsContent and its inner divs, then the alignment is fixed, but there is spacing between gsLeftBorder & gsContent as well as gsContent & gsRightBorder

Any ideas how I can resolve this?
