BOY do I know how frustrating that is. At this time I am not sure of that answer, I do know that if you go to another page without opening a new tab you loose everything, but as for spell checking I would recommend iespell.com. Your message can be checked right on the page that you are typing on so there is no need to leave page or open other tab to check spelling. Once you leave the page that you are typing on everything is gone.Suzan
