I'm having issues with the menu bar on the top of my screen. I have customized it a million times. I have no bluetooth hardware that I desire to use with my laptop, and I don't care anyway. I want Bluetooth off, but it always turns itself on. It also keeps appearing on my menu bar and I want it out. Secondly, the displays button keeps dissappearing, and I want my power source information to remain up there as well. It just keeps going away and I have to keep adding it back up there. How do I configure this so it does not keep changing on me?
