[SOLVED] How can a mouse or graphics tablet be restricted to the primary moni

[MJ01]

I have a MacBook connected to a monitor as an extended display. I am using a wacom graphics tablet. I want to restrict the wacom to the primary display only and not move onto the secondary display.
Can the same be done with a mouse?
