What I like to do is to drag the window to the side of my screen and the window would then take up half of the screen so I could have something else on the other half. What used to happen was the format of the page would change so that I could still see things like the search bar, the zoom buttons, etc. Now when I do that I can only see up to half of the 'Back to me' button, and the tree is not centred and some things are out of reach. I also cannot see the top right hand corner where it displays the username, etc.
If I refresh the page, this happens for maybe a second, and then goes back to the more unhelpful version.
Can someone please help and maybe explain how to get it back to normal?
