Even if there were no issues, why bother? There is nothing you want to do that cannot be done with the AH utilities available ingame. AH is very CH friendly. All you are doing is adding more overhead to your system running one more process in the background when you have no need to.
I think most people that had problems were probably close to overloading their system with too much stuff running as it was, but ditching the Control Manager software solved their problems. You cant argue with results.
I'm not bashing the CM. As far as stick mapping utilities, its one of the best available. I also recommend CH to anyone who will listen. My gear is going on 10 years now, and still works great. You just dont need the CM for AH. Its a waste of resources.
