I had PowerCivil on Windows 7 and it worked fine (well, not compared to AutoCAD but that's a different story). I recently got Windows 8.1 and loaded PowerCivil on to it. When I open any .dgn's or .dwg's they do open but the elements jump all over the screen and when I zoom in to them the elements fade away, meaning you can see one end of them but then half way through the screen they actually fade away. Also, I cannot select any one element but if I just do a window select they all select.
Are there compatability issues with Windwos 8.1? My executable file name is: pc081107614en.exe
