AU has a habit of crashing in my browser — "Aw, snap!" — after I have typed most of a long post. Oh well! Nobody got hurt.
I had a friend here who had the same problem. He doesn’t come on here anymore. His solution was to write his post on something else and copy pasta it into the box here. That way, even if it didn’t post, he at least didn’t have to recreate it. It’s just something I know someone else did. Offering it as an idea.
