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.
