virtualbox.org

I'm using a Windows 7 host and Ubuntu 12.04 as the guest and have 2 monitors. It's more of an annoyance then anything but when I expand both of the window panes that Virtual Box create on each monitor that I have and then move between them it acts like each is a window (which it is) and the active one gets highlighted and the non active one dims. This is kind of annoying as I hope they would both stay active. Is there a way to turn that off?

Thanks
