iPhone presentModalViewController touch works on a small part of the view

Question

Hi,

I have a small imageview that is above my main view (it's 50 high)and when i touch it i use presentModalViewController to push a newView controller.

The problem is that when the view controller is presented i can see the entire view, but touches works only on the same frame as the imageview. Wich means that when i tap on the navigation bar button nothing works ...

Do you have an idea why? and how i can solve it?

Thanks
