.menu stylesheet

Hi there
This is my first ever WP installation… so there is a lot to learn…
I am modifying easel for this site and encounter a problem I hope can be resolved.

I would like to be able to separate the behaviour of this 2 menu items:

.menu .current_page_item a – (the the behaviour of menu items in the menubar when its on that page)

and .menu ul li ul li a:hover – (it’s sub menu items)

I am still working on it, but please have a look and share your thoughts

I would like to be able to have round corners on the menu bar but not in it’s sub menu. Works fine when I am not on that page.
But when the user is on the page of a menu bar item, it’s sub menu display round edges too.

best
