    I know that we "agreed" that BRAT is to be frozen in the pro directory.  Do we 
    really want it frozen with the important mistake Djamel found????
    
    I will not do anything until I hear otherwise.  I personally would vote to put 
    in the correct BrMagnetVolume as I think that having the correct current set 
    when you are trying to match tracks is more important than freezing the 
    volume, but I await the advice of the movers and shakers.

    P. S.  It was my coding that was in error.  It was obviously a cut and paste 
    whose changes did not get carried far enough. SORRY!
