... it's dead, Jim.
I was afraid of this... I tried out a preview version of CXGames from one of the Steam threads (TF2, I think?) and it.. does not launch City of Heroes. The application locks up at the EULA window, without actually displaying the EULA.. White box up top, UI fails to respond.
Actually killing Crossover is remarkably difficult at this point, requiring one to go nuke, by hand, something in the vicinity of 10 wine-related threads via Activity Monitor.
Oops.
The release of CX Games 7.2.0 has this same behavior.
Reverting to 7.1.1 for now.
