[Plugin: Shutter Reloaded] cant close large picture

Hi it works fine. You click & get a larget graphic – but it wont then close???

In lightbox you click the black or dark area or picture & it goes back to your page – this doesnt work I have to click the back button on the browser – is that correct ?? Is that how it works in which case does anyone know a better alternative ???
