keyboard bug

Having searched around for answers, I come here to see if anyone has these issues.
In just a few apps the keyboard behaves incorrectly and the only solution is to quit the app and restart. One issue is where the outer sets of keys right and left just don't respond to touch. Second issue is in a newspaper app where the comment box pops up to make a comment and the keyboard is misplaced to one side making it impossible to type.
