MIDI Sync prob

on trying to sync two G4 Powerbooks (10.2.4/10.2.3) via MIDI (Oxygen 8 as the Master on one and MT4 as a slave on the other PB- both running Ableton Live 2.01) we encountered a strange phenomenon:
PB 1 sends MIDI Clock via Oxygen8 into MIDI In 1 on the MT4. Another keyboard is connencted to MIDI In 2 on the MT4. MIDI Monitor displays the incoming MIDI Clock on the slave book arriving on MIDI In Port 1 ot the MT4 as expected. As soon as a single MIDI message is sent from the keyboard (connected to MIDI In2 of the MT4) MIDI Monitor tells us, that the MIDI Clock is received from MIDI Input 2 (Port2) of the MT4, what is obviously untrue. As soon as the master PB stops the MIDI Clock, MIDI Monitor“s Display switches back to "Port1"
This behaviour keeps Ableton Live on the Slave Book losing sync.

Any idea anyone?
Could be a system problem, but who knows...
thanks,
Andre and Kera
