    I have discovered and corrected a serious program coding error in ObsReduce
    versions 1.1 and 1.2, which causes erroneous position reductions of appulses,
    whenever three reference stars are used. 
    
    The error results in the miss-distance being computed as a fraction of the
    separation between stars A and B, instead of stars B and C. This affected every
    single three-star appulse reduction.
    
    ObsReduce 1.2.4 corrects this error. Users who have installed a previous
    version, need only download the new exe file and copy it over the previous
    version, in the folder/directory where it is installed. The exe is located here:
    
    http://www.satobs.org/programs/ObsReduce/ObsReduce124exe.zip
    
    Alternatively, you may download ObsReduce.zip, which contains all except
    ObsReduce's star files, and run the enclosed setup program:

    I apologize for making this error.
