It is a CSS issue Adam. I noticed that as well and had to adjust the adminbar styles to fix the 1px gap between the main list item and its child dropdown list. I don’t remember exactly what I tweaked but I think it was the padding of the top level links so that they filled the entire height of the adminbar. They were 1px too short and that’s what cause the sub-menus to disappear when hovering down to the child list.
