I need to hide the scrollbar on a div that has overflow:scroll; enabled so that the div will scroll with mouse and keyboard but the scrollbar itself will not be displayed.>
You could put the scrolling div inside of a second div with overflow hidden, then just make the inner div a little wider and taller (the amount may vary depending on the browser, however).
Something like this:
#outer {
overflow:hidden;
width:200px;
height:400px;
border:1px solid #ccc;
}
#inner {
overflow:scroll;
width:217px;
height:417px;
}

Edit: Unfortunately you can still get to the scrollbars by highlighting the text and dragging, and it does make padding etc a bit more of a pain, but other than this I think javascript is the way to go.
