hey guys. i'm on win7, just learning this "game" and installed 5. 6, but when I try to open economics I can see it open on my task bar, but aero shows a blank page and clicking on it doesn't do anything. it works completely fine with 5. 54 though. as a beginner I can barely wrap my head around the system map screen let alone recognize additions in 5. 6, so I guess this is more of a heads up than anything. thanks so much for creating this apparent masterpiece.
