Submit when selecting shipping and payment option

Hi,

When selecting a shipping or a payment option in the checkout process, a submit is executed and the process moves to the next page. How can this be disabled? I want customers to see which option they selected befor they move to the next step.
The page in question is here: 181.224.135.107/~florenti/

Thanks!
Michel

... Have found the setting under Checkout ->Auto submit shipping and payment methods selection
