You could try something with CSS to make the subitems always visible. When hovering, the current item gets the class 'sfHover'.
Perhaphs you can add a CSS style to your site something like this:
li.sub.sfHover ul {
display: block !important;
visibility: visible !important;
}
I'm not quite sure about the CSS selector to make it only work for sub-sub items, but I hope this gets you on your way.
