Apart from anything else that may be an issue, you’re using the director class, yes?

That is very, very old and won’t work with Corona ‘graphics 2.0’, because, amongst other things, it uses named anchors (“topLeft”) rather than anchorX, anchorY values.

Unless you want to update the whole of the class to work with modern Corona, I would suggest you jump to the Composer library.

Also, you shouldn’t really be using module(…,package.seeall ) these days!

p.s… when you’ve got round those issues, the next is … you simply can’t have 5 local functions with exactly the same name in the same module, laying it out as you have (buttonPress)
