CSS Dropdown menu for the header- With Categories!

[Doodles]

Hi,

Am hoping someone can help. I have installed this latest version onto my V 1.3.9h of zencart, on my dev site, while we play around with it lots. I have changed a couple of things to facilitate certain bits that I want it to do, and my categories menu, after renaming it, now works on how I set it up within ZenCart.

However, My "Our Stationery" menu, has a slight error. The menu has eight items on it, and six of these have sub-menus off them. However, on the two that do not, when selected, they leave a small background coloured bar at the top of the "cell", for want of a better word. I cannot see where or how this is occurring.

On a second note, I made the font a little bigger across the menu bar, however, as it drops down into the relative dropdowns, the font size decreases.

Any ideas, gratefully welcome, especially as my wife really like the way this menu works for her site!!
