Application Development Software

The Zimbra help states that I should click on Spell Check to invoke a wizard that will check the spelling of an email I am composing. I do not have a Spell Check icon. The Help also shows a shortcut to invoke what sounds like the same wizard of Alt - X. That doesn't seem to work either.

How do I check my spelling of an email I am composing, be it the intial email of a thead or a Reply or Forward?

Thanks,
Daryl
(I am using IE7. I guess if I was using Firefox, the Firefox browser would most likely do it for me, but I'd still like to understand how this is supposed to work in IE7 and why I don't have that icon.)
