BTW: I was able to fix the problem on the Hyper-V, where the second card was not detected - seems it depends which port you plug the dummy in!
Also: LogMeIn is damn sweet!
I know isn't it the bomb! I have it on my IPad and I am managing all my headless miners fast! BTW Some cards work with a crossfire cable allowing you to drop the dummy plug but so far it only works for 68xx that I have.
