- Click in one of the two buttons
- Click on GO
- Wait until the timer resets
- Click again on the same button you clicked first.
- When you click GO again, the timer doesn't start
- But the other button and timer will work no matter how many times you start it.
- But If you intercalate between the two buttons, it never stops working
