Hmmm, this may be because you're using an earlier version of
MacOSX than me. According to the Apple docs, focusStack only
exists in versions up to 10.5.

Can you please try adding the following method to class
FlippedNSGraphicsContext in GUI/Cocoa/Pixmap.py and tell me
whether it fixes the problem for you?

    def focusStack(self):
      return self.base.focusStack()

Thanks,
Greg
