I'm running the latest VirtualBox. When I install guest addition the windows won't fill the screen. Does not work in full screen and the Auto Resize Ctrl + G is greyed out. I have no problem with other VMs. Have tried to reinstall Guest Addition but did not work. Have tried to install the VM again but did not work. What's the solution?
