This has been going on for awhile and Google has been no help. I usually write in either LibreOffice or Bean. No matter which one I use, I'll be in a middle of a document and without hitting any formatting controls, often in mid sentence BANG font style change. No warning. No reason. I'm at a loss. I can change it back, of course, but after awhile it gets aggravating. Does anyone have a clue what could be causing this or how to stop it? I've considered a corrupt file, but if so, where would it be? It's standard, common fonts it's switching between like times, times new roman and helvetica.
