to check if the responder may have changed.

Ok, at least now I know that the first responder can change! ;) Here's
what I did so far:

[center addObserver:self
                        selector:@selector(windowUpdated:)
                                name:NSWindowDidUpdateNotification object:nil];

- (void)windowUpdated:(NSNotification*)notification
{
   NSResponder* resp = [[self window] firstResponder];
   
   if( resp != m_resp )
   {
       m_resp = resp;
   }
}

The only problem is that resp is always null. Where should I get the
firstResponder instead?

Thanks for your help guys!
