Twistie

Hi there, When I click on the Forward button and then go into the email to edit it for sending forward, it has the annoying habit of adding a space before and after everything I edit. For example, if a sentence reads "John needs six month worth of reports" and I click on the word "month" to add an 's' to it, it will come out looking like this "John needs six month s worth of reports" because it adds a space before and after my edit. How do I stop this from happening? Thanks
