Hello,
in my app, i have a menu button to transition you from the puzzle you are in, to the menu. Now all the buttons work fine, until you hit the menu button and go back to the menu. When you try and go back to the puzzle pages, you get stuck. Here is my code, and am i doing something incorrect?
[code]
