Have written an email and can't find icon to perform spell checking.  How do I add the spell check function to the bar?

When I do spell checking and highlight a miss spelled word and click on the correct spelling, I get the following message "Do you want to leave this page? You are about to throw away this message without sending it." My options are to Leave this Page or Stay on this Page.  I click Stay of this Page but the spelling is not corrected. If it makes any difference, my operating system is Vista.
