I spent an enormous amount of time doing a write up, had a lot of photographs of sestertii, hit save and the text disappeared. I will retry tomorrow with a new thread - I had some GREAT photographs of sestertii.
You have my complete sympathy having done it once too often myself. I don't even know what I did and it would have been something to do with a shift key. One article took me so long I didn't have the heart to revisit it. I now write offline in word and cut and paste as the safest option.
