2 problems with menu Lensation

Hello, I'm using the free version of Lensation. The website works perfect, except for the menu. I'm not a programmer so I will try to explain the best I can :) Uat.welster.be Problem 1: When a menu item has a lot of submenu's, the last submenu's 'fall off' the screen by opening and are not visible. Is it possible to let the submenu's click open centered of above the menu-item instead of below? Problem 2: On a small screen or a screen with low resolution, the menu-items open in two columns. The second column however has no background colour so appears as text over the text of the website. Is it possible to add a background colour? Thx already for reading my question :) An.
