I'm scheduled to have AC support update me tomorrow to v9.4.2, and following their directions I updated Windows10 on all five of my networked computers, including three identical laptops. For reasons unclear to me, one and only one of the laptops updated Windows10 to the next major upgrade titled Creators v1072. Thereafter Amazing Charts v8.2.5 was basically unusable on the laptop that Windows upgraded to the Creators version. It would freeze and become unresponsive every hour or so, requiring Task Manager to close, and would only reload after a full computer restart. Even then, it would freeze during the program loading before the logon screen about 50% of the time. I finally had to roll back the Windows10 OS to the prior build to resume working.
