Weird widget issue

Here's my problem...

I Have a dice rolling app that you can choose three different types of dice. I use three widgets to switch which dice are on the screen.

this is the code I use to move my dice on screen after the widget is pressed:

Code:

btMotionState* motion;
   btTransform earth;
   
   motion = _SIO2object->_btRigidBody->getMotionState();
   earth.setOrigin(btVector3(21.724f, 4.471f, 4.686f));
   motion->setWorldTransform(earth);
   _SIO2object->_btRigidBody->setMotionState(motion);

Occasionally, after I press the widget, everything freezes. It doesn't crash. But nothing works. It happens every once and a while. Does anyone know what may cause this?

This is not coming from SIO2 I can assure you

If suddenly your app gets into an infinite loop you can use Activity Monitor + Sample Process, with that you can get a clear idea of what the application is doing.
