How do you get the vinterp Collision detection to work?

Here is a simple level. I have the actor move form its current location to the opposite side of the screen when the space bar is pressed. There are two actors in the way. The main actor simply moves right through them. Each has a spherical collision object in them. I would assume that when it hits another collision object they would either hit each-other and stop moving, or slide around each-other. Neither is the case, it just ignores the other actors.

Is there some check box that I am missing? I have sweep enabled, but it seems to have no effect.

Thanks for your help,
