Description of problem:
If you access Help or Release Notes (possibly others also) in the install screens, their respective Dialog boxes come up.   There is no way to close the Dialog box using the keyboard. The Tab key does not ever highlight or access the Close button, nor does the Esc key or any other key.  Not professional and hindrance to usability.  There should most always be a way to activate buttons, etc. using the keyboard.
