Question

I seem to be getting a crash right after doing [[CCDirector sharedDirector] popScene]. I am not really sure why. Any clues would help, thanks!

Scheduled timer:

tGridTimer = [[CCTimer alloc] initWithTarget: self selector: @selector(gridSlideUpForced2:) interval: sGridSpeed];
[[CCScheduler sharedScheduler] scheduleTimer:tGridTimer];

Bit of CoCos 2d code that appears to be related to crashing:

-(void) tick: (ccTime) dt
{
    if( timeScale_ != 1.0f )
        dt *= timeScale_;

    for( id k in methodsToRemove )
        [scheduledMethods removeObject:k];

    [methodsToRemove removeAllObjects];

    for( id k in methodsToAdd )
        [scheduledMethods addObject:k];
    [methodsToAdd removeAllObjects];

    for( CCTimer *t in scheduledMethods )
        impMethod(t, fireSelector, dt);
        [[CCScheduler sharedScheduler] scheduleTimer:tGridTimer];

Are you cleaning up your timers in onExit or dealloc in your scene class? Could be the scene still thinks some of the schedulers are still running
