More tweaking of anaconda_help annoying part
    
    Grr, with the screen changes and the animations...waiting for
    screen to change when clicking a button doesn't work very well
    as the button animation often counts as a 'screen change', so
    we're still having issues with the stupid animation transition.
    Let's see if this helps.
