Hi/2. I've uploaded a IME's multiple clauses test version of Firefox. Especially, please test this version if you are Japanese users. What you should check in particular, 1. Multiple clauses are distinguished 2. Each clauses are marked correctly 3. Cursor is located properly in a conversion string And if you find any different things about IME-related stuffs from Windows build, let you know me. You can get a test version, here http://www.ecomstation.co.kr/komh/testcase/firefox-10.0.12esrpre.en-US.os2.zip -- KO Myung-Hun Korean OS/2 User Community : http://www.ecomstation.co.kr
