Try a different way to fix KDE live anaconda launch issues
    
    Lately launching anaconda on the KDE live image seems pretty
    unreliable and we're not sure why. My last attempt to fix it
    doesn't seem to be working, here's another effort based on the
    idea it might be caused by moving the mouse from the hidden
    position to the icon and back again, let's try moving the mouse
    close to the icon before we assert and click it...
