I have a routine that presents and then fades a label and a button,

- (void)fadeView:(UIView *)theView {
  theView.alpha = 1.0;
  infoButton.hidden = FALSE;
  [UIView animateWithDuration:2.5
                   animations:^{theView.alpha = 0.0;}
                   completion:^(BOOL finished){infoButton.hidden = TRUE;}
   ];
}

I changed to Lion and Xcode 4.1 and the behavior has changed. The fade occurs 
as it should, but while it's in action my touch controls are unresponsive. 
Formerly, they worked during the fade. Anyone else noticed something like this?

thanks,

David
