After installing MGA 9 successfully, I noticed that changing the windows behaviour (System Settings, Appearance, Colors, Oxygen) can't be made permanent.
After choosing for instance Oxygen (with the nice blue Windows Title), I can only click on the Apply button, but there is no OK button to make my choice permanent.
So after a restart Oxygen is not remembered. The default Breez Light modus with its grey window title shows up.
The same happens with the other Appearance settings: no OK button to make choices permanent.
Is this a bug in MGA 9, or am I doing something wrong?
