What did you write on your main.lua file?

Try to put button and event listener on scene1.lua to go to the overlay scene (scene2.lua) .

Add :

 group:insert(myRect)

inside scene:createScene( event ) in scene1.lua
And try to use different effect like effect = “zoomInOutFade”

the code work when I tested it.

What build of corona sdk you using?
