App crashing after changing view with animations?

[AdamSubach]

Okay soo heres the dealioo!!!! Im using this current code to transfer between views:

-(IBAction) aboutButton {
	
	aboutScreen *screen = [[aboutScreen alloc] initWithNibName:nil bundle:nil];
	screen.modalTransitionStyle = UIViewAnimationTransitionCurlUp;
	[self presentModalViewController:screen animated:YES];
	[screen release];
}

and this method seems to work fantastic with the way my app works, but heres the problem. After I switch into that view I cant switch to another view with out my app crashing!

I can use the animation: UIModalTransitionStyleCrossDissolve instead of: UIViewAnimationTransitionCurlUp and the app seem like i can switch between more views with out any bugs, but it seems like its when im using the animation UIModalTransitionStyleCrossDissolve.

Any ideas to fix this? With still using the animation UIViewAnimationTransitionCurlUp?
