[ccp4bb] Difference in results between v6.1.2 and v6.1.1

[Peter Grey]

Dear CCP4 developers,

I ran the same DM script (solvent flattening + averaging) in CCP4 6.1.2 and
CCP4 6.1.1.  There are differences in the results -  not huge but
significant.
Could you please suggest a possible reason for that ?

Thanks a lot,

Peter.
