Wow. Never did realise the click-to-initiate action. It becomes so second nature that I take it for granted. Thanks for pointing that out, NoNumber.
It is a good idea to separate a website menu from a GUI.
But from the looks of it, it looks just like a website menu so hover action is just what the user will expect from it.
May I suggest that since Joomla 3.0 is using Bootstrap, why not go all the way?
How about making the top menu bar a row of '
Button Dropdown menus'?

Buttons make me click. It's natural.
