The site uses the theme Associates and its navbar. When you click a top level menu the drop down menu appears but if you move the mouse from the drop down to a third level the side menus disappear & you cannot get at them. This behaviour seems to be predominantly via Chrome but I have seen it occasionally on other people's IE.
There is a post where this was solved by decreasing the vertical separation but the setting for VS here is zero so cannot be decreased.
Any ideas please?

The website is at HERE and the problem occurs when you go Enrolments & Programs > Timetables > Weekly
