Has anyone had problems with pushing a ball into a corner and it going through walls in the corner?

EDIT: Nevermind, I figured it out, the sphere model must not be centered in MED vertically. If the bottom of the sphere is on the center mark it doesn't happen.

EDIT2: Actually I didn't figure it out. So the question still stands.

Here is an example of what I am talking about. If you get the sphere forced into the corner it goes through WED walls. I am guessing it has to do with the sphere model, but I am not sure. It seems that anytime that a continuous force is applied by the player on the sphere phent object it will eventually go through the level geometry when it's trapped.

Thanks for any help,
