Now we are getting closer. But this is weird, The variable titleSize gets 
initialised with NSZeroSize and later only changed here


  if (titleToDisplay != nil)
    {
      titleSize = [titleToDisplay size];
    }

Could you add another NSLog line there and report the value of titleToDisplay? 
This looks like either a bug in our NSString drawing code or the compiler 
itself. We really need to get to the bottom of this. Fixing NSWindow is just a 
work around that won’t help you much.
