I'm getting a strange visual bug when viewing a page with the site center in the browser using margin: u auto. In FF, IE7, Safari it looks fine but in IE6 the site shifts to the left by 10 pixels (zoomed and measured in Photoshop). Look at http://img510.imageshack.us/img510/6175/picture4ux.png to see what I'm saying, and this http://img269.imageshack.us/i/picture8zv.png/ is how it looks like in the other browsers.
Any idea what could be causing this? Could use some help geting to the bottom of this.
