The position of icons in the menubar on the top of the ubuntu desktop changes randomly from time to time.
For example I had the user icon (the one with the logoff/shutdown sub menu) somewhere in the middle of the top menubar after installing. After a while it moved automatically to the end of the menubar.
Q1: How can I restore it to the initial position?
Q2: How can I prevent it from moving the icons as it likes?
