I have both Office 2004 and Office 2008. The former is upgraded as far as possible. Unfortunately O2008 is just a disaster inn that its components take forever to load and it doesn't have VBA. Therefore out of necessity I mainly use Word 2004 for my writing.
The other day I had just completed a 10 page section of a technical document, saved it and closed it. I then reopened it to do some final editing and it appeared in Page View with a font size of 36 points!! I went to normal view and the font size was 12 points under Times New Roman font. For the life of me I couldn't figure out went wrong. I closed Word, reopened a blank page and tried to paste the enlarged version into the new document, but no joy. After an hour of fussing with the damn thing, I finally w=quit.
Then I thought of Time Machine. First I pasted a copy of the "enlarged" and latest version into Text-Edit Plus. Then I went back in time to a mu h earlier version, restored it and voila everything was Normal. I hen compared the Text-Edit version with normal but earlier Word 04 version and now I had a clean Word version of my document. I did lose all my equations because Text-Edit couldn't handle the Equation editor in Word.
So, Time Machine was a lifesaver and Word 2004 turned out to have some sort of flaw.
