On two recent occasions I have typed in a message - and when I try to preview it, I'm 'thrown off'! :(
Not only that: The very first time I attempt to reconnect, I'm met by the following message:
"Wrong username or password. You have used up your failed login quota! Please wait 15 minutes before trying again. Don't forget that the password is case sensitive. Forgotten your password? Click here!"
This seeems to happen again and again - very frustrating, indeed!
