Guess I need some help with menu borders
I've been trying to figure all this out on my own for several days, so I guess I need some help now cause I'm at a total loss :'( overall things are going fairly well! I've managed to work out most of the things I want to do. My menus look like this, there's no problems, is just how I want them.

My Favorites menu tho has this white border I can't seem to get rid of.

and then some other windows menus like in photoshop and my text editor and the popup menus on objectdock have this white border too but also they have this white separator.

I love figuring things out on my own! and I've searched and looked at tutorials and guides... this doesn't seem to be covered anywhere, hoping somebody might take the time to give me a few clues.
Thanks!
