In order to properly select a secondary captcha service (to send to when prinary fails):
Do I select the secondary service in the Captch Breaker options, or in the GSA-SER options, or both?
Thats how it should work. If the host file is modified, it means that someone else is receiving the captchas and not the chosen service.
CB can deal with that as it resolves the host differently.
Uncheck the simulaton of deathbycaptcha in CB and it should work fine.
