Made a thing - was trying to test FB app/plugin with a view to making all my games website based with a FB link for scores /achievements etc.

It does the FB login thing okay, but is not posting highscores yet.
I got another weird thing with the buttons, am just using touch and 'tap' or 'hold' - the engine recognises they are being touched, but the 'tap on sprite x' and 'hold over sprite x' don't work.
