    Still testing...network
    
    
    But testing continues....
    
    Shuffle modules....and back again...no fault ...then fault ("") comes
    back....Or has it got something to do with the mem and when the system
    is down for a while the Memory holds no residual.....????
    
    
    
    
This happens on two different systems  (PIER02 and ROGG02
