As discussed above, the patch is well tested and there are no reports, after (sometimes) weeks of use, that it would introduce new issues. Based on my (limited) understanding, there is no or neglegible regression potential involved.

The problem was repeated several times, even several times. Only now I was able to report a bug, because after each restart of the session, error reporting program was closed. Podczas normalnej pracy, nagle, bez żadnej konkretnej przyczyny, sesja została zrestartowana. Problem powtarzał się wielokrotnie, nawet kilka razy. Dopiero teraz udalo mi się zgłosić błąd, gdyż po każdym restarcie sesji, program raportowania błędów był zamykany.
