This is the FIRST time I ever saw an app that ignores keyboard layout (no matter how I switch it: with Alt+Tab or using the language panel in the taskbar)
In Windows 7, jitsi happily ignores the current layout. When I type in the chat window, it's always in Latin.
In Windows XP SP2, jitsi locks up if I try to switch the layout (again, no matter the method). It also causes the keyboard switcher to stop working and sometimes, the Explorer application to crash -- which equals to the system becoming unusable as there is no way to restart it by typing "explorer.exe" if the layout is stuck on Russian.
If I simply copy&paste Russian text from another application, jitsi has no issues working with it.
What did you do, devs?
