Why do my puzzles take longer and longer to load?
If you solve many hundreds of puzzles you may notice a slowdown in puzzle load time.
Here's how to fix that:
Simply Force Stop Monorail (or Monorail Free) in your Manage Apps Menu.
[NOTE: DO NOT UNINSTALL which will delete your app entirely and lose all your solving progress!]
When you restart your App (after the Force Stop) your puzzles should load much faster once again!
