Hey tdrgg, as far as i see, "tools" isnt even in the menu in office 2007, if thats what youre using.

What fixed my problem was: click the "office button" in the top left corner, then click "word options", then choose the "proofing" tab, and then click "autocorrect options...". In there you can uncheck "Replace text as you type", or you can manually remove the correction you earlier added.

EDIT: I didnt see your last post werhe you wrote youre using word 2003. I cant help you then, sorry m8, and good luck
