   Does cpMouse use a body with infinite mass? It might, but not sure. If so and you connect it to another static body, that's an "unsolvable" constraint mechanism.... aka chipmunk doesn't like it. I'm pretty sure it just throws an assert, you might be able to comment it away, but who knows what that'll do.

   Perhaps theres a way to check before trying to attach to a static... since it wouldn't be able to move anyway.

   @mobilebros. thanks for reply... I got your point, But now what can i do to resolve this.. any idea about it...?

   Is there any way to decide the touched body is static or not..?

   Well usually static bodies have an infinite mass, so that'd be a quick way to check.

   if (shape->body->m == INFINITY)
   {
        //its a static object
   }

   I'm not too familiar with the implementation of cpMouse, so I'm not sure its something you can intercept or not.
