Ok, so I got a bit confused here, memory's not what i used to be, LOL. Curve is a window style and menu issues are probably a widget style thing. But I just tried to replicate the problem on my new 64 bit install and can't. Yet I always had this on VL7 32 bit. What I am not sure about is if it happened right after installation, or only after upgrading some XFCE stuff. Anyway, try changing the widget styles around and see what you get.
