CB Sidebar and IE 8

I tried to fire up my development application today and discovered
that the sidebar doesn't work with IE8 (go figure right). Any ideas on
how to fix it? The only thing I got with debugging was that "cbox is
not defined" on line 257 or something. I checked out the
coldboxsidebar.js file, but am not totally sure what I should've added/

Thanks Accelero, I will report it as a bug.
