Well I've set my compatibility options to Word 2000, but looking at the list of things in there, I doubt that it'll make any difference.
I've also looked in the save options, but there isn't a "save as Word 2000" option, only save as Word 97, which I can't do because I know there are things I do with tables (merging cells vertically for example) that will be mucked up.
Looks like spending money is it
