Is there a way to disable the sidebar scrolling?

The way I've tweaked RTM on my desktop (firefox + greasemonkey), I have a long sidebar/tag cloud, and scrolling prevents me from seeing the bottom of the list (unless I'm at the bottom of the page already).

I got around this in the past with the greasemonkey script Disable Sidebar Scroll ( http://userscripts.org/scripts/show/68011 ), but at some point it seems to have stopped working. Are there any alternatives?

Anyone know how to fix the code? It's pretty short (see below), but I don't know much about JS programming:

if (!unsafeWindow) unsafeWindow = window;

var L = unsafeWindow.document.getElementById("detailsbox");
L.moveDiv = function () {
var L = unsafeWindow.document.getElementById("detailsbox");
L.style.top = window.pageYOffset+"px";
unsafeWindow.Autocomplete.handleWindowResize();
};
