We are also running on Windows machine. Even on a i7 machine, we sometimes have the issue that the program is very slow to response. Usually a reboot and close some open programs (tabs) in EV3 software and other programs running on the background will help. It seems like a computer resource or poor memory management issue. Hope it helps.
