div positioning problems

[pea3698]

I'm having the good old browser problem. I have a verticle bar that I want positioned at 162px left. In ie it works great, in firefox there is a shift of about 3 -4 px toward the right. is there a way to get around this. A friend suggested adding _LEFT:162px but that didn't change anything.

code in header

#rule-1 {
	position:absolute;
	LEFT:162px;
	}

code in body

<div id="rule-1">
<IMG SRC="images/short_horizontal_rule.gif">	
</div>
