Theming the way a panel looks.

I am not sure if this is a support issue/lack of knowledge of the module or if it is a bug.

I've installed Views, and have that working great. I've created a view custom views. Now I am trying to use Panels to grab one of these Views, plus some blocks. The Panel resides at news/737. When I go to that URL The view and the blocks show up in their respective areas. But. Other regions also show up. I thought that a Panel was a customized look, if I didn't include something, it wouldn't show up. however this doesn't seem to be the case.

Is there something I am missing? Is there a way to make sure other regions also don't show up?

_{It's almost like the normal page is rendered and then the Panel is rendered on top of that. If that makes sense.}
