My LibreOffice Writer has worked well for years. But a week ago it started to boot up with two pages on the screen, and in the wrong font. I always use Liberations Serif 12 point and a single page but it now defaults to two pages across the screen and a font that I cannot identify. Whatever I do - including uninstalling and re-installing - I cannot get it to go back to the single page and font that I need. After a few minutes I get a message that LibreOffice is not responding that invites me to quit, and I then have to recover the document. When I do recover it it comes up correctly - single page, correct font. I run LibreOffice on an HP Pavilion running Ubuntu 16.04. I’d attach screen shots to illustrate the problem but I don’t yet have enough points to do so. Can anybody please tell me how to fix this?
