Problem with font size in Catogories menu

Hello!
I'm setting up a shop at:
http://www.carlmanevent.se/shop/index.php

I'm now trying to sort out the font size on the product names, which are in the Categories column to the left.
I know I am supposed to do this in css/stylesheet.css

However, to me it looks as if the top product "¤th of July" still looks small compared to the others.
And yesterday the rest of the product names looked big and nice, but today, they looked small until I clicked on one of them, and then they all got big, except "4th of July".

What do I need to enter ini stylesheet.css to get "4th of July" to be the same font size as the other products?
And is it possible that my settings have made all the text small until you click on them? (or is it just my browser / cache that is playing tricks on me?)

I have really added a lot in my stylesheet.css now to be on the safe sida, but I still have these issues:

/* categories box parent and child categories */

A.category-top, A.category-top:visited {
font-size: 1.1em;
text-decoration: none;
}
A.category-links, A.category-links:visited {
font-size: 1.1em;
text-decoration: none;
}
A.category-subs, A.category-products, A.category-subs:visited, A.category-products:visited, A.category-links:active {
font-size: 1.1em;
text-decoration: none;
}

/* categories box parent and child categories */

P.category-top, P.category-top:visited {
font-size: 1.0em;
text-decoration: none;
}

P.category-links, P.category-links:visited {
font-size: 1.0em;
text-decoration: none;
}

P.category-subs, P.category-products, P.category-subs:visited, P.category-products:visited {
font-size: 1.0em;
text-decoration: none;
}

.category-products{font-size:1.0em;
}
.category-subs{font-size:1.0em;
}

/The main content classes/

.categoryListBoxContents {
font-size: 1.0em;
}

Perhaps your computer is storing your 'old' data... try clearing you cache. :)

The size looks correct to me.

Hope that helps,
