I installed it in vmware and was surprised to see that both the installer and the OS seamlessly grabbed and released the mouse at the window border. The window also autosized when I changed the guest resolution. I don't recall those features working in Ubuntu or any other VM without manually installing vmware tools. Is that a vmware update or OS package convenience? Either, it's smooth.
