No one knows what causes this. MS is trying to reproduce the issue so any
additional information may help. It's clear that the problem is corrupted
font caches in the OS (or caches perceived as corrupt by Word), but not all
machines show this problem, so it's very hard to track down what causes it
and keeps re-causing it.
Here, some questions for all of you--maybe we can identify some common
factors among the people having this problem that would help focus on
possible causes. I'm just brainstorming, so maybe this will trigger
suggestions of other possibly related factors.
How did you do the Tiger upgrade? Upgrade, Archive and Install, Erase and
Install?
Exactly what version of Word are you running?
Do you see the problem in all OS X user accounts?
What if you log in with the shift key held down (disables user startup
items)?
What if you launch Word with the shift key held down (disables user
customizations)?
Any font management software besides Font Book in use in either Panther or
Tiger?
Any programs that give you a different Font menu in use in either Panther or
Tiger?
How many fonts installed? (approximate is fine)
What major programs have installed fonts? (e.g., I have the OS fonts, Office
fonts, and Adobe Creative Suite fonts--this is not really findable
information, but presumably you would remember if installing programs
suddenly produced a big leap in the number of fonts you had available)
What version of Panther did you upgrade from?
Are you currently seeing the problem in Tiger 10.4.0 or Tiger 10.4.1, or did
you see it in both?
