Tablet users- disable trackpoint necessary?

[Fortunate]

When in slate mode and using my pen, the back of the screen hits the trackpoint and causes the mouse to jump, Inking is interrupted. This happens all the time. I removed the eraser head on the trackpoint and the problem went away.

I am wondering if others have this issue?

Any ideas on how to automatically disable the trackpoint when in tablet/slate mode?

You can disable it from the Device Manager in Windows.
