Since updating Libre Office I have not been able to open the Writer page full screen , how do I change this?
Depends on what you mean by “full screen”. If you want the LibreOffice application to fill your entire desktop, then click the single square on the top right of your application window.
If you need the document you are working on to be larger in your application window, go to View | Zoom and change settings there to your needs.
@robleyd; I would suppose the question is about the ‘View’ > ‘Full Screen’ mode (toggle with Shift+Ctrl+J by default). But I have no suggestion how to solve the issue.
Thank you that worked, I thought I had gone through everything…apparently not…missed the obvious!
