Lists/Bullets appear different in FF vs. IE

I made a menu using list styles which shows up perfectly in FF, but badly in IE.

There are problems with the borders and with the bullet images, which you can see in this jpeg here:

i want it to look more like this:

maybe someone can give me some advice?

this is the CSS:

#sectionlinks {
background-image: url(images/menu_img.jpg);
background-repeat: no-repeat;
background-position: right top;
height: 315px;
width: 196px;
float: left;
margin: 0px;
padding: 0px;
font-size: 105%;
padding-top: 10px;
}

#sectionlinks a {
display: block;
padding: 0px 0px 0px 0px;
color: #17253E;
text-decoration: none;
}

#sectionlinks a:hover{
background-color: #E5E3E0;
font-weight: bold;
}

#sectionlinks a:active{
font-weight: bold;
}

#sectionlinks ul a:link{
display: block;
list-style-position: inside;
}

#sectionlinks ul {
margin: 0;
padding: 0;
text-align: left;
margin-left: 21px;
list-style-image: url(images/bullet_link.jpg);
line-height: 150%;
}

list-style-image: url(images/bullet_link2.jpg);
}
