I have over a dozen thread prefixes set up for one section. Can browse them fine on PC browser but on iPad Safari I only see the first 10 and can't scroll through them all to select any after position 10.
iPads and all iOS devices don't allow scroll boxes. It is just the way iOS runs. It's crap, but it's the way it is. I'm hoping that with the iOS 5 update they will add this, but I doubt they will to be honest.
