--- Comment #19 from Michal Suchanek hramrach@centrum.cz 2009-04-26 03:54:43 --- Yes, with a font link I was able to see the Japanese text in the application but not the Latin text (this includes both the initial Latin text and the Latin letters shown by the IM). So I guess bug 18044 probably applies here or there is another similar problem.
However, the IM finally works as expected - I can type kana and kanji in the application.
So I guess the IM problems are fixed in 1.1.15 but font problems remain.
