I have an Ipad 2 and recently when surfing the web, it has developed an odd behavior. If I am on a website, such as this forum, and click the back button to return to the previous page, it will take me back to the page from an earlier date, maybe several weeks ago. If I hit the refresh button, it does refresh to the current page. Any ideas as to what might be causing this? It is rather annoying. Thanks for any help.
