Go to the Toolbox and select the layout tab. Select a Runscreen (e.g. Run 6) and select VT2x6 option to setup in the screen. If you go to the runscreen 6, you will have your VT application and with a single click on the button you can switch the runscreen.
If you haven’t setup you VT application in the runscreen, you will always have to return to the home screen and there select the VT button. Which costs you a little more time.
It is adviced to delete this file.
