I have a UIBarButtonItem opening an action sheet to offer users choices about what to do. Everything works as expected unless I try to click on the "Cancel" button. The target of the button appears to have moved up from where it should be. I can only activate it by clicking somewhere in the middle of the "Cancel" and "Ok" buttons.

I've tried at action sheets in other applications and they work fine, so it's not just my big thumb. The action sheet is opening in a UIViewController

- (void)showOpenOptions
{
UIActionSheet *sheet = [[UIActionSheet alloc] 
	initWithTitle:NSLocalizedString(@"Open link in external application?", @"Open in external application")
	delegate:self
	cancelButtonTitle:NSLocalizedString(@"Cancel", @"Cancel")
	destructiveButtonTitle:NSLocalizedString(@"Open Link", @"Open Link")
	otherButtonTitles:nil];

[sheet showInView:self.view];
[sheet release];
}
