Onscreen keyboard won't disappear after use.
After using the onscreen keyboard it frequently stays up and there doesn't seem to be an y way of making it disappear except by quitting the page I'm on. And I can't find anything in the manual to fix it.
To add to this, I did find that tapping on a different area of the page I'm on will usually make it disappear. But in one app at least - Words with friends - only changing the orientation will do it, and not always then.
I don't understand why there is not a button for disappearing the keyboard, as there is in the iPad.
