I managed to get iFrame/HTML-object scrolling on the iPad (iOS 5.1) to work. But there are still some problems.
One such problem is, that when I scroll the iFrame around the iPad screen it seems that the render engine of Safari isn't able to reload the content of the area - and that it just becomes visible before scrolling. Hope everyone understands what I mean. You can try it here It's a very basic page just to demonstrate the problem. Has anyone here encountered this problem and has a solution?
