Rogi, after a conversation with him i can tell it isn't a fault of operating system and graphic card. it's only during the game so i think it's a fault of any valid script of a WA, maybe during the game an error has occured by any computer virus or just an error of OS. Chel, you installed the newest update and rubber and it didn't help so maybe any line in file requires to change. in my case always helped install a newest update or other. the last decision was a re-install of WA, but make a back-up your maps, schemes, etc after. or maybe it just requires change a resolution in WA?
or just try to update your graphic card driver?
