Spry Vertical Menu Border Issue IE8

Hello, I recently noticed that on sites that I have created incorporating the Spry Vertical Menu have a border display issue in IE8. While the CSS border displays on all four sides of the outermost container of the Menu Bar in IE 6/7 as well as Safari and Firefox, it only displays on the top of the menu bar in IE8.

On closer inspection, it appears that the border is collapsed at the top of the menu bar in IE8. Any help with a solution for this issue would be greatly appreciated. I am using Spry Version 1.6.1.

The relevant CSS for the border is:

	border: 1px solid #CCC;

An example of the problem can be seen at: http://www.vacation-pictures.com/hawaii-2010/

Thanks in advance for any help!
