a:hover problems

[deric.cain]

i'm having some trouble when hovering over any of the buttons in my menu. they look fine until i hover over them and the background color goes outside the border. if i cahnge the width on them then my words move when i hover over them. i'll paste the a, a:hover below. any help is appreciated.

/* Menu */

#menu {
margin-bottom: 19px;
border: 1px solid #999999;
background-color: #f4f3f3;
}

#menu h2 {
display: none;
}

#menu ul {
margin: 0;
padding: 0;
list-style: none;
line-height: normal;
}

#menu li {
display: block;
