Hard to describe what happened after I downloaded and installed the latest version (7.6.4), except to say that Writer is no longer usable. I can’t select any text with the mouse. The screen fractures into chunks of text, making it uneditable. I cannot even save a new document.
So, I uninstalled it and all associated files from my Mac (OS 10.15.7) and installed version 7.5.9, but the problem persists. I can’t recall if that was the version that was working before or not, so please advise if I need an archived version of LO to work with Catalina.
