[Fluxus] OSC not working in Lion?

[ron millar]

Hey there,

I'm working on an important project.  OSC works awesome in 10.5
 but when I try to send a message to my 
Lion Mac(s) the signal is not received.  Localhost 
stuff works fine.  Just won't accept an external signal. 


(osc-source "8000")

(every-frame
   (with-state
      (when (osc-msg "/knob1")
        (translate (vector 0 0 (osc 1))))
(draw-cube)))

Using variants of this and (display (osc-peek))(newline) 
I can see this works on my 10.5 mac but not my 
two 10.7 ones. 

Any help would be great. 

Thanks

Ron
