If you install it, you get a new menu called "toys". Clicking on this you'll have the option of showing the toolbar or disabling it. Provided you remember to click on "save settings" right at the bottom you'll never see it! I can tell you, though, that WordToys has been rock solid under Word 2003 - I've had it installed for three years plus and have never had any problems with it. Hope it works out for you. You'll get a 30 day trial of the Pro version which will revert to the freebie if you don't pay for a licence.
