I have tried to change my mining pool several times to something other than ghash.io, and it keeps reverting back. While it may really like that pool I have tried to change to bitminter and multipool.us without success.
Why does it hang onto the ghash? How do I make the changes stick?
It is very frustrating.
Thanks.
