Weird object throw problem

I am not sure if anyone else has seen this before but I have an interesting issue. When I throw an object, any object that can respond to a collision (vehicles, rigidshapes, ect..) that I am looking directly at are sucked towards my character if I contiunue to hold the mouse button after the item has been thrown. My code is standard throw code as you can see.

function ShapeBase::throwObject(%this,%obj)
{
   // Throw the given object in the direction the shape is looking.
   // The force value is hardcoded according to the current default
   // object mass and mission gravity (20m/s^2).
   %throwForce = %this.throwForce;
   if (!%throwForce)
      %throwForce = 20;

   // Start with the shape's eye vector...
   %eye = %this.getEyeVector();
   %vec = vectorScale(%eye, %throwForce);

   // Add a vertical component to give the object a better arc
   %verticalForce = %throwForce / 2;
   %dot = vectorDot("0 0 1",%eye);
   if (%dot < 0)
      %dot = -%dot;
   %vec = vectorAdd(%vec,vectorScale("0 0 " @ %verticalForce,1 - %dot));

   // Add the shape's velocity
   %vec = vectorAdd(%vec,%this.getVelocity());

   // Set the object's position and initial velocity
   %pos = getBoxCenter(%this.getWorldBox());
   %obj.setTransform(%pos);
   %obj.applyImpulse(%pos,%vec);

   // Since the object is thrown from the center of the
   // shape, the object needs to avoid colliding with it's
   // thrower.
   %obj.setCollisionTimeout(%this);
}

A little help would be appreciated.
