Collision detection with haptic pen

[mjabon]

Hello. I can get collision detection to work on normal objects, but when I try to use it with the haptic pen it does not trigger the event on collision.

I try to just make collide spheres on both a box and on the pen's marker. However, when I move the marker with the pen such that it touches the box I get no collision event. Why is this? How can I detect the collision of the pen with an object? Do I have to just use the haptic pen's touch objects?

Thanks!
