Falling through the floor when debugging?

When running tutorial 6.1 in debug mode, I fall through the floor.
This does not happen while not debugging.
Has anyone else seen this problem?

When you are debugging change the time step to be constant, like that you can debug frame by frame.

In example:

Code:



   sio2PhysicRender( sio2->_SIO2physic,
                 1.0f / 60.0f, 2 );   



Thanks, works perfectly.
