Thank you for reply, the solution you provided works well, though there are no any relations between firefox and our app.

I've sent you package to povided e-mail address. We have license and use latest full version 4.20.

Greetings!

I have a strange problem with protected app. Text input fields in protected app duplicates russian input - english letters are ok, but russian prints twice per one keystroke. How can It be fixed?

P.S. App built using Qt 5.2 + VisualStudio 2012
