I am creating a game in Flash and I am creating a main menu for the game (With buttons like 'Play', 'How to Play', 'Hiscores' etc.) and was wondering what is the best way to go about it?
All of my Actionscript code is in external .as files and I've used classes throughout but I was having trouble figuring out how to get it so that the menu will be shown as soon as the game is ran. The main problem is that there are timers in my game that have event handlers attached to them and I was trying to think of the best way to essentially stop these timers until the user actually clicks 'Play', otherwise the objects spawn over the top of the menu and the timer ticks down.
Would stopping the timers but then adding an event handler to the play button to start the timers be a good idea? I am trying to figure out the best way to do this for future reference.
Thank you for any assistance.
Edit: Tried Cherniv's advice, getting some errors.

}
My menu is a movieclip named myMenu and the class is set as Menu but I get errors such as:
Main.as, Line 50 1120: Access of undefined property playBtn
I gave the button an instance name of playBtn before I converted the menu to a movieclip so not sure what's going on there. I'm probably missing something really easy but it's a bit confusing for me after typing all day.
