I did make note of all my system settings, Eileen. The thing that has changed is the default view of the Live Control window. No matter what I do or how I set the Memorize functions, it never displays the sliders as the default view after selecting another registration. Before the update, it always displayed the sliders in the Mixer, no matter what or when I changed registrations.
That may not be part of the System settings but whatever Gremlin is in that update, it sucks! I started a thread on that months ago and none of the solutions worked to restore the default view. At this time, before a playing session, I have to manually select the Mixer settings in the Live Control window and press Freeze. Sometimes I forget to do that before a show and look up at the Mixer and see a different set of settings.
Funny thing is, if I press the Registration button twice, the correct display is seen. This NEVER happened before the updates!! It's a real nuisance.
