BuddyPress.org

Hi there I’m looking to style all of the corners of the buddypress admin bar that drops down in the top right hand corner, so they’re rounded. Can anyone help me with the css? I’ll paste in below what I’ve got so far: I patched the below together using firebug & a paste from somewhere (the change admin bar with more effects bit which gives me a white dividing line between dropdowns although none of the rest of it seems to do anything) Can anyone help? I’m really stuck! Many thanks
