I am not sure why this is doing this but I changed the theme to a different color for the main content other than white and when I hover over the menu (any category within the menu) it goes tot he selected color I choose for the hover effect but when I leave the hover and it returns to normal it actually displays a white background around the category name. Example shown in attachments. The only way for it to return to normal is to reload the page. I also noticed this happens when I hover and leave hover on the shopping cart (top-right) area (Attached as well below). If this can be fixed that would be fantastic!

Again this happens only after I hover for the item and then leave the hover and only in the main nav and shopping cart areas. I fixed the little home icon by going to photoshop and opening the sprites.png and removing all the white around the icons.

All the best,
Marcus
