I am a brand new owner of a MCX8000. When I use the right screen to look at preferences by holding down the view button I get stuck on that screen. I can see who I hit view again that the SELECT knob is manipulating Serato but on the screen is still system preferences and the cursor is not moving to high light new options. The left deck screen works fine.
The only way to get the unit from being stuck on this screen seems to be a power off and on of the system. Not real practical if I ever decide to try to play in public again
