Hello.
I have seen that in the template Ja_University leaves a space between submenus that is very annoying when browsing because there are times when you can not go to that submenu because it disappears as it detects that the mouse is not on top of the menu.
So I know this problem is of the template since I have installed the demo and it has this same problem.
