scrollsToTop not working

Hi

I'm aware you can't have more than one scrollsToTop-able view open, otherwise the functionality breaks - you must only have one view with that set.

But I cannot get this working despite going through my entire code with a fine tooth comb and setting every text area, scroll view, table view and web view to scrollsToTop: false And then setting just one web view to scrollsToTop: true

Is there anything else that is known to break the scrollsToTop functionality?

Developing for iPhone.

Thanks.
