Menu Appearance

You can configure the appearance and behavior of context menus and standard application menus here.

Under Animation, you can specify whether menus should fade out when they close. You can also select a display effect from a drop-down menu.

Under Effects, you can specify whether Windows should use flat 2D menus or whether a small 3D shadow should be displayed beneath an open window.
