I'm using Windows 8.1 Single Language with Punto switcher.
When I switch language in a Jitsi's chat window from EN to RU, then Jitsi freezes and restart. It frezees only for EN->RU, for RU->EN works well. If I do not use a Punto, Jitsi works well, but I need Punto.
I read topics about Punto switcher from this mailing list, and should say one thing. No other software never conflicts with Punto switcher, but only Jitsi. All of Java-based programs work well with Punto switcher, but Jitsi freezes. This is a very bad position, because many of russians use Punto. I like Jitsi and try to use it every day, but this little bug give me a some doubts.
Please fix this bug. If I can help, I would happy to help )
