strange force when applying colliders
 

Hi,
i have a problem when applying collider to a sub object,
i try to drag the object with mouse and make it collides with other objects .
but when i use room.collideSphere(-1,"p1") and drag p1 it starts acting crazy,
also without colliders when i drag it for the first time it drags well, but if i tried to drag it another time it will go crazy and i dont know why..
can you please help me?

It's possible you have two objects that are in a constant collision with each other.
