Host Panel overlaping guest on full screen on dual monitors

[jhr1979]

Have 2 Linux desktops that are running Linux Mint 17.1. One is running xfce.
Running VirtualBox 5.0.4 with guest additions
Guest system is Windows 7 and Windows 10

On both of these systems when I make the guest go full screen it goes full screen, however the linux panel/taskbar keeps coming to the forefront and overlapping my windows taskbar on the opposite screen than I'm currently working on.
This is a real problem as I need to be able to watch notifications via the programs in the taskbar on the guest machine. Any way to get around this? At a real loss here. Didn't have this issue at all with a previous version of VirtualBox.

If you notice on the attached image on the bottom Left Screen it shows the Linux taskbar and the Right Screen shows the Windows taskbar. I just want it to show Windows in Full Screen. Previously had this working now can not get it to work for the life of me.
