UIScrollView eating touches from its parent

Question

I have nested scrollViews (or rather a subclass of UIScrollView inside of an actual scrollview). I set the size of the inner view to its contentSize and set scrollEnabled = NO, because I only want the outside view scrolling. But the innerView occasionally eats touches and keeps the outerView from scrolling when it should.

Is there something else I need to set to keep it from stealing the scrolling touches, but still allowing user interaction (e.g. editing a textView)?
