Overflow: scroll works in different ways in various browsers. See
http://www.quirksmode.org/css/overflow.html
and
http://www.x-smiles.org/demo/testsui...lowscroll.html
However, the way you have it the scroll will apply to all divs which is probably why you are seeing it in another place.
Give the code to a single div class:
in stylesheet or head:
<style>
div
.testscroll
{ background-color:#00000;
width:500px;
height:150px;
overflow: scroll
}
</style>
in the body
<div class="testscroll">Test - add a lot of text here to test the scroll</div>
