OK, I am going crazy here..... I just updated to 385.69 the latest driver.... Now, when I start Mastercam my system automatically turns off the Aero Desktop......previously, there was a setting you can set to turn it off...on this system I have always run with it on and it didn't affect me...so I am looking through the Nvidia Control panel and can find nothing... Does anyone have a hint how I can disable this feature?
