[PD] OSC to SuperCollider

[Paul Crabbe]

Hello
as I'm a new user of PD, I hope I didn't miss something obvious:

I use the compiled OSX version 0.39.0 (on Tiger)
I'm trying to connect SuperCollider and SC with OSC .
It actually works OK from SC to PD. (dumpOSC receives data from SC)  
so I suppose the OSC objects are valid.

The problem is that I can't send anything from the sendOSC object,  
even if I try to communicate from PD to PD
e.g.
the two help files 'sendOSC' and 'dumpOSC' are opened:
     I send the 'connect localhost 9999' message to the sendOSC  
object, then I try one of the send messages in the helpfile ('send / 
test/bla 1 2 3')
   -> I always get the error message : "SendData::SendHTMSocket() 
failure -- not connected"



Where should I look for?
Thanks!
Paul
