    Set a breakpoint on the line, and starting with `My`, check each item for `Nothing` – A Friend Jul 27 '16 at 09:21
  • I've experienced this before when using a `StringCollection` setting. To fix it: Go to the `Settings` tab in the application properties > Select your `History` setting's third column and press the `...` button > Write something in the first line to add an item > Press OK > Press the `...` button again > Remove what you wrote in the box > Run your application > No more error. – Visual Vincent Jul 27 '16 at 10:24
