Have a look at this.......
Spell checker for everything You download it and it can be used on anything that you are writing from. I just hit F11 now and it comes up and spell checks what I have just typed. It works on any programme. All you do is make sure your cursor is in the text-box you are writing in and press F11. It comes up then and spell checks for you. The best thing about it is it can be used anywhere i.e. chat rooms, replies to forums like this, anything in fact as long as your cursor is in the box as explained above..........
