To demonstrate OSX's Chinese language capabilities I moved Chinese to the top of the language list in System Preferences > International. I got this to work fine, and all the menus etc come out in Chinese (I'm a bit of a Chinese scholar you see). Now I want to revert to English (for my normal working life) and when I try to open System Preferences it just crashes and says the application failed to open. It says do I want to try again. I do this and it crashes again. The third time System Preferences does finally open and it seems that I can reinstate English. I get a message saying do I want to use the new settings or keep the original ones. I have tried both these options but OSX is still refusing to change back the language settings. I have tried it many many times, rebooted the powerbook a bunch of times, always the same - seems like I'm stuck with Chinese!!! Help!
