Dang Chris, you are on it!
Already thought of hasLayout and that’s not it. I’ve tried to change a few different things about the layout / stylesheet for IE6 to no avail. It’s like the browser is just forgetting to move all items that are positioned absolutely. There is another little image on the page that is on the same level as the expanding content’s container which is also not moving anywhere…just getting run over by the expanding content.
