Just emailed CS with the above problems just wait to see about the chirping low volume multi tone noise. The windows 10 / win 7 updated pc (gaming) I had to run in compatibility mode, but the win 8.1 laptop version ran ok when tested it on that (also running Win 10).Cured the non wheel led/gear display now I can access the properties page as well.
Have fixed the driver properties problem by deleting and re installing V219 driver.
