Never happens while I am working, only appears after I wake the pc from sleep (nobody else uses my pc.) Oddly, it never goes to Windows default bottom of the screen, only to the right hand side. This year, in version 1803, it started moving by itself to the right side of the screen, regardless whether I have it “locked” or not. I like it on left of my screen, has been my preference for many years. I believe there is a bug in Windows 10 that moves the taskbar by itself.
