Removing/Resetting Timers for Game
Greetings fellow Flashdevelopers
My friend and I are trying to create a small Flash game for school but we're stuck trying to reset it when you have a Game Over.
The timers keep going on the Game Over screen and when you press the back button they keep going on the menu screen aswell.
We're trying to look for a solution to fix the issue.
We're also trying to find out how you make the game completely reset when you press the back button, so that you can start a new game without any issues.

This is the AS3 script we wrote for the game. I highlighted the places in red where we tried to write some code for the Game Over screen.
