i have been using "yu c" cantonese input since xp. works on vista and win7 as well. i uploaded it to sendspace. give it a try and you'll love it : )

1. unzip the file
2. drag miniime.tpl and uniime.dll to C:\Windows\System32
3. right click eyw2k.exe, click run as administrator to install
(it should work on other input methods too. simply drag those two files to system32 and try install yours cuz "yu c" was pretty hard to get used to at the beginning cuz it integrated some english and 速成 in it)
