Hello Matt. Thanks for your email. Yes, at the time I wrote the post below, I had already reset and restarted the language under Intl Preferences.
The problem is resolved, but not without a lot of pain. I had to take the computer back to Apple dealer and they explained that the problem is that in Taiwan, they install a component under MacOffice to enable the UserInterface in Chinese language. (Just FYI: Along with the computer, i purchased MacOffice Home and Student Edition (not a bootleg copy), which looks like its only in English, no chinese language anywhere on the box). They had to remove the MacOffice Chinese language component from the computer. They did this, which fixed the User Interface problem, but then subsequently all the information I had on my computer was gone. (Note: although the UI issue was resolved, there were still components under Word which were in Chinese.) Apparently they were unable to restore it b/c the information was written over (vs being erased). For some reason, whatever component they removed was connected with my data.
When I got my computer back after 24 hours, Entourage kept freezing and asking me if I wanted to report the error to microsoft (which I did, many times). Then entourage refused to start up, saying my database was corrupted. I followed all the instructions and tried to rebuild my database, which kept failing. I finally gave up and brought it back again to the apple dealer. They took out everything, and then re-installed everything. I asked them to use English for everything from the very start, and not to monkey around with installing the chinese component like they do for other buyers in Taiwan.
I have been a user of pc my entire life, and now switching to Apple after hearing rave reviews from all my family and friends, I've been quite let down by the experience.
