Can't change keyboard layout in Spark

Windows 7 SP1 x64

Spark 2.7.2.695 (Russian)

Java 8 Update 31 (both x32 and x64)

After some unspecified action users are no longer available to change their keyboard layout in Spark.

Layout letter does change to Russian, but text in the message window is typed in English.

Restarting Spark solves the problem just for a few minutes.

Updated: Spark 2.7.7.810

The problem still exists.

Same problem Re: Spark не пишет по-русски But wasn’t able to reproduce or find out the cause.

As there are 2 reports now, i have filed this to track easier [SPARK-1733] Keyboard layout switches to English from Russian - IgniteRealtime JIRA

Greetings!

Can you provide any diagnostic recommendations on our part?

No, have no further ideas hiw to investigate or reproduce this. You can try the latest build to see if the issue is still there (though i doubt it will help). Keep in mind that this build has bugs, so it is onky for testing http://download.igniterealtime.org/spark/dailybuilds/spark_2_7_7_859.exe

Is there any difference with 2.8.x versions?

Any feedback about 2.9.3 version? Maybe it is fixed already?
