No wisecracks from me—I ran Word 4.0 and 5.1 on the same computer for years.  It was the rare case where msft didn’t damage a file when opened with an older version.   I didn’t always need the new features, and 4 was *far* leaner . . .

Also, to say something on topic . . . note that OSX is kind of ham-handed on file types.  As near as I can tell, you can’t change the default application manually without applying to all files of that type at the same time.
