And I've seen adults have trouble with some of those (myself included).

That maybe because on some OS's you can't make any window have focus
or even move others about at anytime. Those two "features" are
probably the most annoying thing of that OS. Followed closely by
opening a blocking dialog box *behind* everything else on the
desktop.
