Doc or Fahlcor (Since you said you had it working)

I have setup a west hash account and tried pointing at bit minter but I keep getting
"Error: Extranonce1 size and extranonce2 size greater than 8"

I have modified the worker with different difficulty settings from 16 to 128 and tried the override of
stratum extranonce2at 4 and 8.

But keep getting the error.

At another pool I had no issue with an order.

Thanks in advance for hints of the secret sauce to make it happy
