Disabling the touch screen

[peter-h]

I have the Lenovo Tablet 2 and to prevent accidental touching I would like to kill the touch screen, until a button on the side is pressed.

The software must be fairly simple: capture the screen messages and throw them away.

One would keep the digitiser pen active and just throw away the touch screen messages, ideally.

Has anybody seen such an app?

There is this http://code.google.com/p/touch-toggle/ for windows 7 but windows 8 is different in various areas.

I can't find a Tablet 2 forum here - apologies!
