HOw to Pause A Game in Action Script 3.0?

hi,

i would like to know on how to pause a game in as3, i did b4 to put the stage frame rate to zero(0)

and it actually working. but what i wanted to have is a drop down menu. when the esc button (27 in ASCII code) was pressed a drop down menu will pop down and the game paused.

i did this code but not working :

if(e.keyCode == 27)
{
menuDown.play();

 if(stage.frameRate == 24)

{
stage.frameRate = 0;
}

 if(stage.frameRate != 24)

{
stage.frameRate = 24;
}

}

it pauses but the driop down menu wont come down bcoz the frame rate is zero,

hope somebody can help me here.

thanks in advance…

cheers,
