There were a couple of CSS flaws in this theme, and I"ve just released a fixed version. Nothing major - in IE6 the menu did not position correctly, and the post navigation looked wacky with long titles. All fixed now, though!
If you downloaded and installed this skin already, you only need to upload rarrow.gif and larrow.gif from the images folder, the single.php file and the stylesheet.
So sorry for any inconvenience to anyone using this theme.
