The mouse was lagging. Fullscreen really wasn't full screen. So I enabled scaling (mouse still dragging). But now vbox menus gone. and winkey c won't get me out of this mode.

1.8.5. Resizing the machine's window
You can resize the virtual machine's window when it is running. In that case, one of three things will happen:
If you have "scale mode" enabled, then the virtual machine's screen will be scaled to the size of the window. This can be useful if you have many machines running and want to have a look at one of them while it is running in the background. Alternatively, it might be useful to enlarge a window if the VM's output screen is very small, for example because you are running an old operating system in it.
To enable scale mode, press the host key + C, or select "Scale mode" from the "Machine" menu in the VM window. To leave scale mode, press the host key + C again.
Please see Chapter 14, Known limitations for additional remarks.
If you have the Guest Additions installed and they support automatic resizing, the Guest Additions will automatically adjust the screen resolution of the guest operating system. For example, if you are running a Windows guest with a resolution of 1024x768 pixels and you then resize the VM window to make it 100 pixels wider, the Guest Additions will change the Windows display resolution to 1124x768.
Please see Chapter 4, Guest Additions for more information about the Guest Additions.
Otherwise, if the window is bigger than the VM's screen, the screen will be centered. If it is smaller, then scroll bars will be added to the machine window.
