How do I get this on click event to work properly?

Why do I have to click the start button several times on the start page ?

It's hard to tell without seeing the capx. Maybe the page is still loading in the background? Perhaps switch to a different frame on the button when it's been clicked, at least that way you can tell whether it's because the button isn't registering or because there's a delay before loading the next layout after the click has been registered.

Check the collision polygon shape of the button sprites. Maybe the "guessed" shape got mangled up and you need to shape it manually.

Thanks guys. I initially added a sound action to the click but it became quite annoying to have to click the button 3 times and still not going to the game. The collision poly is OK. The coding is a simple on object clicked??? Any more ideas???

if the button is definitely registering the click then try adding a loader layout and make sure all sounds are preloaded, rather than starting on the Home screen.
