Hi, I'm attempting to create a drop down menu with css and javascript and the effect are very different between browsers. When I hover over a form in Firefox, it highlights the menu perfectly. However, when I hover over a form in IE, it does not highlight. I was wondering if anybody can help me with this. Thanks so much.

Here's the css:
#dd li form.menu
{   display: block;
    background: #5970B2;
    padding: 4px 10px;
    margin: 0 1px 0 0;
    color: #FFF;
    text-decoration: none}

#dd li form.menu:hover
{   background: #49A3FF}
