I am using latest version of jQuery Autocompletion plugin and have populated an array (as input for autocomplete) of about 800 entries. Now strangely when I type a letter which triggers large results (causing a scroll bar), I can see a scrollbar in Firefox but not in Internet Explorer.

I have only included the files `jquery.autocomplete.css` and `jquery.autocomplete.js` in my JSP. Should I need to include anything else?

**Edit:** my CSS is as follows:

```
.ac_results {
    padding: 0px;
    border: 1px solid black;
    background-color: white;
    overflow: hidden;
    z-index: 99999;
}

.ac_results ul {
    width: 100%;
    list-style-position: outside;
    list-style: none;
    padding: 0;
    margin: 0;
}

.ac_results li {
    margin: 0px;
    padding: 2px 5px;
    cursor: default;
    display: block;
    /* 
    if width will be 100% horizontal scrollbar will apear 
    when scroll mode will be used
    */
    /*width: 100%;*/
    font: menu;
    font-size: 12px;
    /* 
    it is very important, if line-height not setted or setted 
    in relative units scroll will be broken in firefox
    */
    line-height: 16px;
    overflow: hidden;
}

```
