--- Comment #3 from Ilya 141400@mail.ru 2008-03-19 13:12:31 --- The real reason of this bug is xneur - automatic keyboard switcher. I stopped service 'xneur' and all keys work fine. Then added "Wine" to the list of excluded program in kxneur and run the service - everything work great in this case.
