This, I suspect, is the most likely explanation to the OP's problem: it wasn't active fixer in the fixer tray... Any fixer at all for even a short time will give some protection - to fade within seconds suggests no fixer at all to me. I flash-fix RC test strips for 10-15 seconds (fibre 30s) before turning the light on (film strength rapid fixer) and they do not generally fade noticeably at all during the session.
