Do you get a download notice when you click on the spellcheck icon?
I didn't know that, but I guess it's because I already have that software installed.
Yes, I would recommend it. It's a nice free piece of software (
www.iespell.com) and you can use it on any site once it's installed. You won't get the spell check icon obviously, but you can right click in any text window and select "check spelling".
