This example uses mootools but I see the same behavior with scriptaculous.
I have a div with some content, in this case a single X and there's plenty of white space around the content. I make the div draggable but I find it's difficult to drag the div in IE. In IE I need to click and drag directly on the content of the div, the single X. If I click in the div, but away from the X, the div just sits there.
It behaves as expected in FF, Chrome and Safari.
Here is a complete working example with mootools. You'll have to update the script tags to reflect what you named your mootools libraries. (on edit I added a scriptaculous example as well)

}
#my-drag p{
text-align: center;
}
</style>
<script type="text/javascript">
function start() {
var e = $('my-drag');
e.makeDraggable();
}
</script>
</head>
<body onload="start();">
<div id="my-drag">

Here's the same example using prototype scriptaculous - same issue
