I'm using 2.1.4 on OpenBSD. While editing a large file (book) I've twice had it suddenly corrupted which made it impossible to edit. Doing anything, such as inserting a space or deleting a letter, causes the whole para to be struck through (horizontal lines through the text) and the text changes colour. There is also a vertical line on the right.
Oddly I can still make PDFs when this happens but it is no longer possible to change anything in the file. I don't know what I did preceding the change but it's happened twice. I spent many hours trying to fix it but in the end gave up and replaced the file with a slightly older one from offline backup. So far this is OK. Any ideas about what could cause this? I tried reinstalling lyx but the problem didn't go away. -- Anthony Campbell http://www.acampbell.uk
