Wndows 7 Host Ubuntu 12 Graphics Driver Unknown

[VirtualTestr]

Hello

I have a windows 7 host running the latest VirtualBox 4.1.20 and I just created a 12.04.1 Virtual Machine. I went through the process of mounting the Guest Additions and installing the VBoxLinuxAdditons.run file. Everything looked alright and it even said that it installed the graphics drivers, but after rebooting the Graphics Driver still said "Unknown" with running in Experience "Standard" mode. Did I miss a step here? As it seems that it should have installed the VirtualBox graphics driver?

Any help would be appreciated...

thanks
