DIV Background Won't Scroll Along

Works fine in IE6, though in Safari, Firefox, and Opera, the bg inside this div doesn’t scroll… so weird!

<style type="text/css">
	div {
		width:200px;
		height:50px;
		overflow:auto;
		background:url(images/spreadsheet/column.gif) scroll;
	}
</style>
<div>
	test<br />
	test<br />
	test<br />
	test<br />
	test<br />
	test<br />
	test<br />
	test<br />
</div>

I want the BG to scroll along… what did i do wrong?
