Thanks John,

I have those options set on each share as create mode = 0660 and 
directory mode = 0770.  I tried adding 'force' to those lines but the 
problem appeared to get worse.  Is the 'force keyword important or is 
this two ways of saying the same thing and any change was purely 
coincidental?

many thanks
