I have ZC (1.3.6) set up for authorize only, however, transactions are being captured. I just spoke with Authorize.Net and they said that shortly after the initial auth request, a second request is being sent for '[FONT=Arial, Helvetica, sans-serif]prior_auth_capture'. Is there anything in ZC code that would generate this message?

TIA.
