Please see url: http://wp.woodensun.com/. One the navbar, go to What We Sell > Fireplace & Hearth > Wood > Woodstoves. You can see, starting with 'What We Sell' and 'Fireplace and Hearth', the top border of 'fireplace and hearth' is not flush with 'what we sell'. As you expand out to 'wood' and 'woodstoves' there is an extra pixel of space with each subsequent menu list and I don't know why (see attached). Can you help??
