Which browser are you using so I can test this?
Regarding losing content; In the past if you typed a message and then your computer crashed or you had finished typing out a reply and there was a connection issue after you hit submit, then you would lose the post. This version of the software saves your post locally in your browser every few seconds and the content will remain. You should therefore never have to start from scratch unless you're using a really old browser. You can even log out, restart your computer mid way through posting, come back a week later and your draft reply will still be waiting for you.
