Initially I had set up two "opendns" servers that I use on this computer 
as well as the ISP's suggested server, and here I also use 
caching-nameserver.  All of this an attempt to reduce the effect of 
system delays inherent with this satellite ISP.  Anyway I reduced 
resolv.conf to just the ISP's dns when I began to recognize this problem.

Ok, knowing that I think I will reinstall.  I am aware of possible 
problems and will use extra care in my responses to the install menu items.

I thank everyone for their suggestions and help.
