When I was a T-38 Flight Instructor, we used to sit around and debate the same issue (ad nauseum) with regard to a failed engine. Would a windmilling engine turbine generate more drag than a frozen turbine? The answer came from our USAF test pilots and engineers at Edwards AFB. The windmilling engine will cause more drag.
I like Noel's idea to prove it to yourself. Get any little prop at the local hobby shop or make a wooden one and go prove it for yourself. You could even put some resistance on the prop and see whether a slowly turning prop is worse than a free spinning one. I done this and the fast spinning one is the worst case for drag.
cheers,
