...But there is no Spellbound extension for Fx3 and I cannot turn off the spell checker even though the box to use it in Options/advanced is unchecked. I also cannot turn it off on the Vista machine. I have to right click uncheck the "check spelling" box every time I go to make a post. Then when I preview the post and want to change something, add something, the spell checker has been turned back on. It is awful. It is like a leech that cannot be dislodged....
