Thank you so much, SB65! Huge improvement! It still sits underneath the breadcrumbs but I'm sure I can solve that.
I am curious, though, whether there's a way to make the mouseoever a bit easier. It seems like I have to maneuver my mouse directly over the arrow at the top of the drop down in order to get to those menu items. I would prefer to be able to just drag my mouse from wherever on the main menu item I happened to be (which would still be along the length of the drop-down), and get to the sub-menu. Does that make any sense?
