Quick scroll UIWebView the web view falls down

[zzndino]

Scroll UIWebView down to refresh, before loading finish, scroll down again (actually my action is do the scroll down one by one without waiting) the WebView falls down, means top of web view falls down every time I scroll down and never scroll up back to original place.

I'm seeing the same problem. My UITableView never returns to the same place, and gradually shifts down 20 pixels or so every time I pull to refresh.
