I have selected 'compose int HTML' and have selected 'large Helvetica,Arial' as my working font. Regularly, while creating an email, I will delete a letter or do something and the editor reverts back to the original 'default' font and size. Why? and how do I stop that? I also have a multi-line HTML signature file which is added to the email. If I accidentally delete the last character of the message body so that the signature wraps up to the line I am on, it loses all line formatting i.e. it goes from a 7-line signature to a 1-line signature and I have to edit that. Why can't the signature be a 'protected block' at the end of my email and not be affected by my editing?
