title: Corona storyboard goback to scene
body: <p>I have a timer in my <code>play.lua</code> that when it hits 0 it goes automatically to <code>timeend.lua</code> which indicates that its time's up. But when I close the scene of <code>timeend</code> (by a button) it goes to <code>menu.lua</code> but does not function well. When I touch play button in menu it shows nothing but the background. </p>
