Firefox starts locked up whenever SCIM is running. No browsing is possible at all. No response to either mouse or keyboard.
If I exit SCIM, Firefox works normally. But that is not a good workaround, since Japanese input in Firefox is not possible, and not possible in other running programs either while Firefox is running. And like many people, my browser is running all the time. This is a longstanding problem with all Ubuntu users, at least since 2007. Is there a fix or a workaround?
Running Ubuntu 12.04 LTS
Is this still a problem? Can you please try with the latest upstream 1.4.17 available from http://archive.ubuntu.com/ubuntu/pool/universe/s/scim/scim_1.4.17-1.dsc ?
