Ever since the update to Mac OS X 10.4.6 installed (flawlessly), my version of Microsoft Word 2004 started crashing on me whenever trying to open an existing document. I tried everything I could think of (short of reïnstalling the system - we're not Windows, after all), but nothing helped. So, this morning I decided to ask the Support Forum at Apple, and guess what: I had a solution within 4 hours! Thanks, Whoopy!
The solution consisted in - arcanely enough - replacing the new (sic!) version of the German Hyphenation Dictionnary files with an old version. How sick is that!?! One more proof that you want to eradicate whatever Microsoft infestation you have on your system!
