Garib and all!

I have always kept the hydrogens on in all my refinements using refmac.  
Starting with refmac 5.1.24 however, refmac behaves very badly if do 
generate all hydrogens.  My R-factors go up like crazy and lots of 
complaints on uncorrect -H distances.... I initially panicked, but later 
switched off the H generation with "ignore even if present in file" and 
everything works fine.  IS this a Linux specific bug or am I doing 
something wrong. I have tried with all kinds of resolution structures 
starting from 2.1 - 1.4...
